I’m a total hoarder when it comes to scrap wood, so with my heap of off-cuts growing by the day, I finally turned those tiny bits into a striking piece of DIY Scrap Wood Wall Art that you can arrange and rearrange however you like.

I envisaged a mosaic-style panel by gluing scrap wood of every shape and size onto larger boards. Because I planned to paint the entire piece, using dirty or previously painted off-cuts didn’t matter, though you’ll need to sand them if you’d rather showcase bare timber.

Those tiny off-cuts from my barn quilt projects proved perfect. For the base, I repurposed old bed slats, then raided my workshop and craft room for odds and ends. And if you’re painting yours, don’t feel limited to wood alone—I incorporated anything I could find. Below, I’ll break down every item I used.

Materials Needed

• Assorted scrap wood pieces (various shapes and sizes)
• A straight base board (e.g., repurposed bed slat )
• Mitre saw (or hand saw)
• Full-size hot glue gun & black hot-glue sticks
• Black gesso (or black spray paint)
• Paintbrush
• Silver metallic wax paste
• Clear gloss spray sealant
• Assorted mixed-media embellishments:
  • Old buttons
  • Broken drawer pulls
  • Glass beads
  • Upholstery studs
  • Thumbtacks
  • Resin squares
  • Half pearl beads
  • Halved ping-pong balls
  • Wooden curtain hoop
  • Wood appliqués
• Velcro Command strips or keyhole hinges
• Safety gear: gloves, dust mask, eye protection

Scrap Wood Art Base

For the base, you’ll need six long boards. I repurposed recycled bed slats and scraps from my scrap heap.

• 2 x 1.3m x 7 cm
• 2 x 1.1m x 7cm
• 2 x 35cm x 8.5cm

I set out to shrink my ever-growing scrap-wood pile—I can’t bear to throw away any off-cuts. Since I began woodworking in 2012, I’ve spent almost nothing on new timber, relying almost exclusively on reclaimed materials. Nearly every project on my blog is built from recycled materials—read this post to discover exactly how I do it.

Cut the wood to size

I used a mitre saw to cut my off-cuts quickly, but you can use any saw—it’ll just take longer. Keep each piece under 3 cm thick so they don’t stick out too much. If you want to make it more interesting, cut some pieces at different angles.

Attach Wood to the Base

I used hot glue instead of wood glue so the pieces would stick firmly when hung on the wall. Grab a large glue gun and black glue sticks so the glue won’t show through the paint. Hot glue is strong—I’ve used it on my barn quilts—and if you need to remove a scrap, you can chip it off with a hammer and chisel. Don’t sand rough wood; the rough bits look more interesting once painted. This step takes a few hours: start at the top and glue the small wood pieces onto the board in no particular order.

The plan is to affix a variety of wooden shapes onto the base, layering different forms and textures to build a mosaic-style collage.

Add Textures with Mixed Media

Stroll through your workshop and craft stash to find embellishments. I tucked in buttons, studs, beads, and appliqués into gaps. You don’t need fancy items—every piece will unite under a coat of gesso. The peppering of objects creates depth and intrigue. Here are some of the items I used.

• Old buttons
• Broken drawer pulls
• glass beads
• upholstery studs
• thumbtacks
• resin squares
• half pearl beads
• Ping pong ball cut in half
• wooden curtain hoop
• wood applique

You can zoom in on the images below to see how I layered and used everyday items to create different textures.

It may look a little chaotic now, but once you paint it, all the elements will blend into a cohesive work of art.

Paint with Black Gesso/Acrylic paint

Brush on a rough coat of black gesso, embracing imperfections. Messy strokes highlight wood grain and glue textures. If you have black spray paint, feel free to use that instead for a quicker finish. Allow at least an hour to dry completely.

I thought it looked interesting like this, but I wanted to add the silver to highlight the texture.

Highlight with Silver Wax Paste

I picked silver because it suits my home décor. Wax pastes come in many colours, but if you don’t want to buy different tins, you can make your own at home—see the recipe in this Post.

Use metallic silver wax paste to highlight the raised areas. Dip your fingertip into the wax and gently rub it over the raised surfaces—don’t cover all the black or the effect will be lost. For tight spots, use a small, soft paintbrush to lightly apply the wax.

The photo below shows how rough painting adds texture. I just slapped paint on the ping-pong ball and the chevron wood piece. Messy hot-glue trails look great, too. After you apply the silver wax, let it cure for 12 hours.

Seal and Hang

Spray two even coats of clear gloss sealant to protect the paint and wax. Once dry, mount on the wall using Velcro Command strips (holds up to 4 kg) or keyhole hinges if you don’t mind wall holes. When you tire of the design, easily swap or remove strips with no damage.

Close-Up Details

Taking photos outside was hard because the metallic wax reflected too much light, and the indoor lighting where I hung it is poor. Here are some close-up shots of the final finish.

You can hang these panels horizontally, vertically, or stagger them—whichever layout you find most appealing.

I used this same technique to create this mirror for my kitchen. You can also find inspiration in my other unique woodworking projects.

If you love this idea but aren’t into woodworking, you can achieve a similar effect by using cardboard instead.
