Before you toss those old wooden picture frames gathering dust in the garage or sitting in a thrift store bin for next to nothing, stop and reconsider. Most people look at a battered wooden frame and see only what it was — something to hold a photo or a painting. What they are missing is what it could become with a little creativity and almost zero investment. Tying four matching or similar wooden frames together at their corners is one of those ideas that sounds too simple to work until you actually try it, and then you cannot believe it took you this long to discover it. The result is a stunning, functional piece that transforms completely depending on what you choose to do with it.

Wooden picture frames are one of the most overlooked raw materials in DIY crafting. They come with their own structural integrity already built in — four sides joined at right angles, often with beautiful detail work, molding, or distressed character that would cost a significant amount of money to replicate from scratch. When you tie or join four of them together at their corners, those four separate frames suddenly become a three-dimensional box shape that can serve as the foundation for a lantern, a garden planter display, a shadow box, an outdoor decorative structure, or a tabletop centerpiece that looks genuinely expensive and completely custom. Here is exactly how to do it, along with the best ideas for what this surprisingly versatile project can become.
What You Will Need
- Four wooden picture frames of matching or very similar dimensions (the closer in size and style, the more polished the finished result will look)
- Strong twine, leather cord, jute rope, or zip ties for binding the corners
- A drill with a small bit (optional but useful for cleaner corner attachment)
- Sandpaper for smoothing any rough edges
- Paint, stain, or chalk paint if you want a unified look across all four frames
- Hot glue gun for reinforcing connections if needed
- Additional materials depending on your chosen project (see below)
How to Prepare and Join the Four Frames
Start by removing the glass, backing board, and any hanging hardware from all four frames. This not only reduces weight and bulk but also gives you cleaner corners to work with. Lay all four frames out flat and compare them — if there are significant differences in depth or molding detail, decide which sides will face outward before you begin joining them, since you want the most attractive sides visible in the finished piece.
If you want all four frames to look unified, this is the moment to paint or stain them. Chalk paint in matte white, black, or a soft sage green gives a beautifully rustic finish. A coat of dark walnut wood stain over a sanded frame brings out the grain and gives the whole piece a polished, intentional look. Apply your chosen finish, let it dry completely, and then lightly sand if you want a distressed effect that makes the piece look like something you would find in a boutique home goods shop for four times what you spent.
To join the four frames into a box structure, stand them upright on their edges and arrange them so that each frame forms one side of a square or rectangular box. The front face of each frame becomes one visible side of the box. At each corner where two frames meet, use your chosen binding material to tie them securely together. Thick twine or jute rope wrapped several times around the corner joint and knotted tightly creates a beautiful rustic connection point that becomes a decorative feature in itself. If you prefer a cleaner, more modern look, use small hinges or corner brackets on the inside of each joint instead. For the most secure connection, pre-drill small guide holes through both frame edges at each corner and thread your twine or cord through before knotting.
Project Idea 1: An Outdoor Garden Lantern
This is probably the most dramatic use of the four-frame box, and it genuinely looks like something you would buy from an upscale garden or home decor store. Once your four frames are joined at the corners into an open box shape, you need to create a base and optionally a top. For the base, cut a piece of thin plywood or a wooden board to fit the interior dimensions of the box and attach it to the bottom of the frame structure using wood glue or small screws driven through the frame edges. Sand and paint or stain the base to match the frames.
Place a pillar candle, a battery-operated LED candle, or a small string of battery-powered fairy lights inside the box. The open frame sides allow light to filter beautifully through all four sides, casting warm, dappled light through any glass panes you choose to re-insert, or glowing softly through the open frames themselves if you leave them without glass. For an outdoor version, drill a few small holes in the base for weather drainage, insert a waterproof LED candle, and hang the finished lantern from a porch beam or shepherd’s hook using a length of heavy-duty twine or metal chain attached to all four upper corners. These lanterns also look extraordinary grouped in threes on outdoor steps or along a garden path.
Project Idea 2: A Tiered Hanging Garden Planter Display
For this variation, you do not necessarily join all four frames into a closed box structure. Instead, join two frames at their lower corners only and attach a piece of mesh screening, hardware cloth, or a thin wooden shelf across the bottom interior of each pair to create a shallow tray. Then use ribbon, twine, or chain to suspend one pair below the other at a comfortable distance, creating a two-tier hanging display. Line each tray with coconut coir liner or a piece of burlap and fill with trailing plants, small succulents, herbs, or seasonal flowers.
This works beautifully on a covered porch or in a bright corner of a room, and the frame edges give the whole thing a polished, finished look that a simple wire basket planter cannot match. You can customize it endlessly — paint the frames to match your outdoor furniture, stain them to complement your porch decking, or leave them in their original painted or gilded state for an eclectic, collected look.

Project Idea 3: A Decorative Centerpiece Box or Shadow Box
Join your four frames into the complete box structure and add both a base and a top if you want a fully enclosed display case. This becomes an extraordinary shadow box or a tabletop display for seasonal decorations, collections, or natural elements like pinecones, dried flowers, seashells, or stones. For the holidays, fill the interior with battery-powered lights, ornaments, evergreen sprigs, and ribbon for a centerpiece that works on a dining table, a mantel, or an entryway console. At other times of year, fill it with a small potted plant, a collection of candles at varying heights, or a curated arrangement of meaningful objects.
If you add glass panes back into all four frames before joining them, the finished box becomes a display case that protects its contents while still allowing everything inside to be fully visible from all four sides. This is a genuinely beautiful way to display a collection of small antiques, pressed botanicals, or any treasured items that deserve a proper showcase.
Project Idea 4: A Decorative Outdoor Garden Feature
Four frames joined into a tall, open box structure — with no base or top — can be placed directly in a garden bed as a decorative garden feature. Spray paint them with rust-proof outdoor paint in black, bronze, or forest green. Set the finished structure over a flowering plant to create the effect of a plant stand or garden focal point. You can also use the four-frame box structure as a support for climbing vines or small flowering climbers by pressing it into the soil and allowing plants to grow up and through the open frame sides. As the season progresses, the frames become increasingly covered and integrated into the garden — beautiful from early spring when they are most visible, and equally beautiful in summer when the planting has filled in around them.
Tips for Finding the Right Frames
The very best sources for this project are thrift stores, estate sales, and yard sales where wooden frames can be found in large quantities for very little money. You do not need four frames that are perfectly identical — frames that are similar in overall size and profile but slightly different in molding detail or finish can actually create a more interesting result once they are all painted or stained the same color. Look for solid wood construction rather than thin MDF or plastic frames, since the wood needs to have enough thickness and strength at the corners to accept a joining connection without splitting.
Avoid frames whose corners are already separating or whose wood feels soft and punky, since these will not hold together reliably through the project. Frames with broken glass are perfect for this use since you are removing the glass anyway — in fact, broken-glass frames are often marked down even further at thrift stores, which is a genuine bargain. Ornate frames with heavy plaster or resin detail work can be heavy, so consider whether the finished piece will need to be portable or supported before choosing very elaborate styles for a project like the hanging planter that requires the structure to bear additional weight.
Why This Project Works So Well
What makes this particular DIY idea so satisfying is that it converts something genuinely worthless — an old wooden picture frame without a purpose — into something that would cost a significant amount at a boutique decor shop, using almost no skill beyond the ability to tie a knot or operate a hot glue gun. The frames do most of the work simply by being what they are: pre-finished, detailed, structurally sound wooden rectangles with built-in character. Joining four of them amplies that character into a three-dimensional object that reads as designed and intentional rather than assembled from salvaged materials.
It is also one of those projects that scales beautifully in complexity depending on how much time and effort you want to invest. At its simplest, you are tying four frames together with twine and placing a candle inside. At its most elaborate, you are building a multi-tiered hanging garden display with reinforced joints, painted frames, and custom-cut bases. Both versions are impressive. Both versions cost almost nothing. And once you have made one, you will find yourself looking at every old wooden frame you encounter in a completely different way — not as something worn out and heading for the trash, but as raw material waiting for its second life.
