Cheap Ways to Decorate an Old St. Louis Living Room, Starting With: Don’t Sand the Radiator
Revised November 7, 2026
What are some cheap ways to decorate my living room?
Start by editing, not buying. Clear the surfaces, pull furniture off the walls, and swap in warmer bulbs. Then spend on the few things that change the whole room: curtains hung high and wide, a rug big enough to hold the furniture, fresh pillow covers, and art you actually like, even thrifted prints in new frames.
Keep reading ↓Don’t sand the radiator. In an old St. Louis living room, that’s the first cheap decorating rule, and almost no decor guide mentions it. The sofa’s fine. It’s everything around it: a bare plaster wall above the cushions, a radiator painted three shades of cream under the front window, trim with a chip in it right where the vacuum always hits. You bought the place for the brick and the tall ceilings, and now the itch is to scuff, scrape and repaint your way to finished.
Here’s why. The City of St. Louis Health Department names lead-based paint and dust as the most common source of lead exposure. It was used in many homes built before 1978. Those homes are the majority of housing stock in St. Louis. Scraping old layers off a radiator is how paint becomes dust. If a child under six or a pregnant woman lives in a City home, the Lead Inspection and Hazard Control Division inspects it free of charge. Request it online, or call the Citycall the Citizens’ Service Bureau at (314) 622-4800rsquo;s CSB line at (314) 622-4800. When lead hazards are found, owners may apply for financial assistance.
The brick is the other thing worth knowing. St. Louis turned to it early: the City’s own preservation plan says the growing town had stripped away all the timber within a ten-mile radius by 1812, and the first brickyard in St. Louis opened a year later. So that warm, uneven wall behind your sofa, cool under your palm, comes from a very old local habit. Count it as a color you already own, not something to cover.
The moves that change a room most never need a scraper. Clearing surfaces, adding lamps, hanging curtains high, buying the rug big, swapping pillow covers, hanging art from the picture rail instead of a nail. Below: the cheap moves first, then the designer rules people keep quoting, colors that read expensive, the mistakes older houses invite, and where to shop by type of store. No store names, just how each kind of shop works and what it’s good for.
What are some cheap ways to decorate my living room?
Start by editing, not buying. Clear the surfaces, pull furniture off the walls, and swap in warmer bulbs. Then spend on the few things that change the whole room: curtains hung high and wide, a rug big enough to hold the furniture, fresh pillow covers, and art you actually like, even thrifted prints in new frames.
Editing is free, and it’s the step people skip. Take everything off the coffee table, the mantel and the bookshelves. Put back only what you’d miss. Most rooms look cheaper because of too many small things, not too few nice ones, and a cleared surface with three good objects on it reads calmer than a crowded one with fifteen.
Next, shop your own house. The lamp in the guest room, the basket in the hall closet, the framed print that’s been leaning against the basement wall since you moved in. Bring it all down, try it, and send back whatever doesn’t earn its spot. A surprising amount of the job is already sitting upstairs.
Light it like a room, not an office
One ceiling fixture makes any living room feel like a dentist’s office. Add two or three lamps at different heights: a floor lamp in one corner, a table lamp by the sofa, maybe a small one tucked on a shelf. Warm-white bulbs in all of them. Then turn the overhead off after dark and watch what happens.
Curtains, rugs and pillow covers
Curtains do more per dollar than almost anything else you can buy. Mount the rod higher than the window, closer to the ceiling, and let it run past the frame on both sides so the panels hang against wall instead of glass. The window looks bigger. So does the ceiling. Old St. Louis houses with tall windows reward this more than most.
There’s one local catch. If a radiator sits under the window, floor-length panels will trap its heat behind fabric all winter. Hang the rod wide enough that the panels stack beside the radiator, not in front of it, and use a simple shade inside the frame for privacy.
For pillows, buy covers and keep the inserts. Covers cost less, store flat, and let you change the room with the season. An insert one size bigger than the cover gives that full, plump look instead of a sad flat square. Rugs are the one place not to go small to save money. More on that below.
Art doesn’t need to be expensive to look intentional. Thrifted frames with a fresh mat, a few enlarged family photos, a vintage map, a kid’s painting in a serious frame. What matters is the frame, the scale and the hanging, not the price tag. If the sofa itself is the problem, though, no pillow will save it, and our guide to buying furniture in St. Louis that lasts covers that side of things.
What are the decorating rules designers actually use?
Three come up constantly. The 3-5-7 rule groups accessories in odd numbers. The 60-30-10 rule splits a palette into a main color, a secondary color and an accent. The 2/3 rule sizes art, tables and rugs against the furniture they sit with. None of them are laws. They’re shortcuts that keep a room from looking random.
The 3-5-7 rule, or the rule of odd numbers
Group things in threes, fives or sevens instead of pairs. An odd grouping keeps the eye moving around it, while a pair tends to split into two separate halves. Three candlesticks of different heights on a mantel. Five frames in a loose cluster. Seven usually means a gallery wall or a long bookshelf, and it’s where most people stop.
Height matters as much as count. A tall piece, a medium one and a low one read as a composition. Three things the same height? That’s a row at a garage sale. Mix textures too: something glass, something wood, something with a little green in it.
The 60-30-10 color rule
About sixty percent of the room carries the main color, usually the walls and maybe a big rug. Thirty percent goes to a secondary color, often the sofa, curtains or a large chair. The last ten percent is the accent: pillows, a vase, a print, a throw. The split is rough. Nobody’s measuring.
In an older St. Louis house, count what’s already there. Stained oak trim, a brick fireplace wall, honey-toned floors: those are colors, and they often eat up a big share of that thirty. People forget the woodwork, pick three new colors on top of it, and then wonder why the room feels so busy.
The 2/3 rule for sofas, art and rugs
This one’s about proportion. Art hung over a sofa should span roughly two-thirds of the sofa’s width. A coffee table tends to work best at about two-thirds of the sofa’s length. Some designers stretch the idea to rugs, wanting the rug to reach well under the front legs of every seat instead of floating in the middle like a bath mat.
It fixes the most common eyesore in any living room: the tiny picture hovering over a long couch. If your art’s too small, don’t buy a bigger piece yet. Hang two or three together so the group hits that two-thirds width. Same fix. Far cheaper.
When to break them
Rules help when you’re stuck. They don’t help much when you love something. A single oversized painting, two matching lamps flanking a sofa, a room done entirely in shades of one color: each breaks a rule, and each can look great. Learn the rule first. Then break it on purpose, once, where people will notice.
What colors make a room look expensive?
Deep, muted colors with some gray or brown in them usually read richer than bright, clean ones. Think navy, charcoal, olive, forest green, warm white, camel and oxblood. Layering several shades of one color, sticking to matte finishes and repeating a single metal finish does more for a polished look than any one pricey object.
Why do those colors work? They’re complex. A muddy green or a smoky blue shifts as the light moves across the day, so the wall looks one way at breakfast and another at dinner. Bright primaries stay flat. They look like a classroom, or a toy aisle.
Texture does half the job. A wool throw, a linen pillow, a leather ottoman and a nubby rug all in the same camel family look deliberate. That same color in one shiny polyester fabric looks like it came out of a box. Want the expensive effect without the cost? Stay in one color family and vary the materials.
Brick helps here. An exposed brick wall is already a warm, earthy color with built-in texture, and it pairs well with deep greens, blues, black metal and cream. Don’t fight it with a cool gray.
Color mistakes that cheapen a room
The big one is choosing paint from a chip under store lighting. Paint changes on the wall. Buy samples, brush large swatches onto two or three walls, and look at them in the morning and at night before you commit. North-facing rooms pull colors cooler, and a white that looked soft in the store can turn icy blue at home.
Other repeat offenders: ignoring undertones, so a pink-leaning beige fights a yellow-leaning floor. Collecting too many accent colors, each bought on its own for a different pillow. Going all gray because it felt safe, then finding the room has no warmth left. And painting a small, dark room white in hopes it’ll feel bigger, when a deeper color often makes it feel cozy on purpose.
Which decorating mistakes show up in older St. Louis homes?
The same few, again and again. Art hung too high, rugs too small, furniture pushed flat against the walls, curtains that stop at the sill, and one overhead light doing all the work. Older homes add their own: blocked radiators, woodwork fighting the paint, and plaster walls hammered full of cracked nail holes.
Rugs first. A small rug floating in the middle of the seating makes the whole room look like it shrank in the wash. Ideally the front legs of the sofa and chairs rest on it. In a long, narrow living room in an old brick house, that can mean a bigger rug than feels right. Trust the tape measure, not your nerves.
Furniture against the walls comes next. It feels like it opens up the floor. Mostly it just makes conversation shout across the room. Pull the sofa forward, float the chairs toward it, and let the radiator breathe. Shoving a bookcase in front of one wastes heat, and that dry heat isn’t kind to wood, paper or candles sitting right above it.
Then there’s the woodwork. Plenty of older homes still have original stained trim, and plenty had theirs painted decades ago. Either can look great. What looks off is a room where walls, trim and furniture all compete in different wood tones and paint colors. Pick one lead. Let the rest support it.
The last one is subtler. Everything bought at once, from one place, in one weekend. The room ends up looking like a showroom, tidy and faintly lifeless. Rooms that feel lived-in usually grew over time: something old, something handmade, a thing you hauled home from a trip.
How do you hang art on plaster and brick walls?
Slowly, and not with a hammer and nail. Plaster over wood lath can crack and crumble when it’s struck, so drill a small pilot hole through a strip of painter’s tape and use a screw or an anchor made for plaster. If your house has picture rail molding, you may not need a hole at all.
Picture rail is that thin strip of molding running around the room a little below the ceiling in many older houses. It was built for exactly this job. Hook hangers over the rail, drop cord or thin wire down to the frame, and you can move art whenever you like without touching the plaster. Plenty of owners never realize what that trim is for.
When you do drill, find the lath if you can, because a screw that bites into wood holds far better than one sitting in plaster alone. Heavy mirrors and big pieces deserve extra care, since old plaster can hide loose spots behind a solid-looking surface. If a wall sounds hollow or crunchy when you tap it, move the hole or talk to someone who repairs plaster before hanging anything heavy there.
Brick is its own animal. Use a masonry bit and drill into the mortar joint rather than the brick face, since mortar is easier to patch later and less likely to crack. Height trips up almost everyone. Aim the center of a piece at roughly eye level for a standing adult, and over a sofa, leave about a hand’s width between the frame and the top of the cushions.

Where’s the best place to shop for home decor?
There isn’t one best place. There’s a best place for each kind of thing. Independent decor shops are strong on edited, unusual pieces. Thrift, antique shops and estate sales win on frames, lamps and character. Big-box stores cover basics like inserts and curtain rods. Online works for exact sizes. Most finished rooms mix all of them.
Independent decor boutiques
A good independent shop has already done the editing for you. Someone chose every lamp and vase on the floor, and that eye is what you’re really paying for. Staff can often tell you what pairs with what, hold a piece while you go home and measure, or point you toward a local maker. Prices run higher. Mistakes run lower.
Thrift and antique shops
This is where character lives. Brass lamps that only need a new shade, heavy frames, pottery, old mirrors, baskets and textiles often cost far less than new and look like they’ve been in the family for years. Go often, since stock turns over constantly, and carry your measurements. Our roundup of St. Louis vintage, thrift and antique shops worth the trip is a good place to start.
Estate sales
A city full of older homes means a steady run of estate sales, and they’re a strong source for lamps, art, rugs and mirrors. The first day usually brings the best selection. The last day often brings markdowns on whatever’s left. Bring a tape measure, some patience and a friend with a truck.
Big-box and discount stores
Useful for the unglamorous stuff: pillow inserts, curtain rods, rug pads, frames in standard sizes, bulbs, storage baskets. Where they fall short is the accent pieces. Buy your showpiece there and you’ll probably spot it in three friends’ houses by spring.
Online
Online shopping shines when you know exactly what size and color you need, and it’s hard to beat for rugs in odd dimensions. The risk is color and texture. Screens lie. Order swatches when a seller offers them, check the return policy before buying anything bulky, and look for reviews with photos taken in real homes.
Shop with the room in your pocket
Whatever store you walk into, bring the room along. Photos of each wall, measurements of the windows and the wall above the sofa, and a swatch or two of the sofa fabric and the paint. Holding a pillow up against the real fabric beats guessing from memory every single time.
Keep a running note on your phone of what the room still needs, in order. It stops impulse buys. It also stops the fourth throw pillow.
Room dressed, but what about you? Start with tuxedo and formal wear rental.
Frequently asked questions
What is the 3-5-7 rule in decorating?
It’s the rule of odd numbers: group accessories in threes, fives or sevens rather than pairs. Odd groupings keep the eye moving and look more natural than matched sets. Vary the heights and textures within each group. Three works on a coffee table or shelf, while five or seven suits a mantel, a long bookcase or a gallery wall.
What is the 60-30-10 rule for decorating living rooms?
It’s a way to balance color. Roughly sixty percent of the room goes to a main color, usually the walls and big surfaces. Thirty percent goes to a secondary color in the sofa, curtains or a large chair. The last ten percent is accent: pillows, art and small objects. In older homes, count wood trim and brick as part of the mix.
What is the 2/3 rule for living rooms?
It’s a proportion guide. Art over a sofa should span about two-thirds of the sofa’s width, and a coffee table tends to work best at about two-thirds of the sofa’s length. Applied to rugs, it means going big enough that the front legs of your seating rest on the rug instead of leaving it stranded in the middle.
What colors make a room look expensive?
Deep, muted, complex colors usually do: navy, charcoal, olive, forest green, camel, oxblood and warm whites. Layering several shades of one color family, choosing matte finishes and repeating one metal finish look richer than bright primaries. Varied textures in the same color, like wool, linen and leather, finish the effect without costing much.
What color mistakes should I avoid in my living room?
Don’t pick paint from a small chip under store lights. Test large swatches on the wall and check them morning and night. Watch undertones against your floors and trim, avoid piling up unrelated accent colors, and don’t default to gray just because it feels safe. Remember that wood trim and brick already count as colors in the room.
What are 10 common, but hideous decorating mistakes?
Art hung too high. A rug that’s too small. Furniture pushed against every wall. Curtains that stop at the sill. One harsh overhead light. Tiny art over a long sofa. Cluttered surfaces. A matching furniture set bought in one go. Too many unrelated accent colors. And radiators or vents blocked by furniture, which wastes heat and dries out whatever sits above.
What is the best place to buy home decor?
It depends on the item. Independent decor shops are strongest for edited, unusual pieces and honest advice. Thrift stores, antique shops and estate sales win on lamps, frames and character. Big-box stores cover basics like inserts and curtain rods, and online shopping suits exact sizes. Most well-finished rooms end up mixing several of those sources.
How do you hang pictures on plaster walls?
Skip the hammer and nail, which can crack old plaster. Put painter’s tape where the hole goes, drill a small pilot hole, and drive a screw into the lath or use an anchor made for plaster. If your house has picture rail molding near the ceiling, hang art from hooks on the rail and skip the holes entirely.
