I made my first moon mirror on a whim, mostly because I'd seen one on a friend's Pinterest board and assumed it was a $400 West Elm piece she'd splurged on. When she told me she'd made it herself with a wood round and a tub of joint compound, I didn't fully believe her until she walked me through the actual process — and it turns out "handmade" and "looks expensive" aren't opposites here at all.
There's something genuinely different about a piece like this compared to standard wall decor. By day, it reads as an organic, textured art object. By night, plugged in, it casts a soft, warm halo that changes the entire mood of a room in a way flat overhead lighting never will. This guide walks through building your own from scratch — the materials, the texture technique, the backlighting wiring — plus what to look for if you'd rather buy a ready-made version instead.
"Harsh overhead fixtures trigger alertness; indirect, warm ambient light signals the brain to unwind, making this piece ideal for bedrooms or cozy reading nooks."
If moody, ambient lighting is the part that appeals to you most, our Cozy Apartment Ideas Under $100 guide covers more low-cost ways to layer warmth into a room beyond this one project.
This project genuinely does not require prior woodworking or crafting experience. The forgiving part is the plaster texture — it naturally hides small imperfections in a way that clean, precise woodworking never would.
01 / Why Organic Texture & Backlighting Work
Interior styling has shifted noticeably away from stark minimalism toward something warmer and more textural — organic modernism, Japandi, and soft maximalism all share a foundation of grounding tactile materials. A moon mirror fits squarely into that shift: rough plaster crater textures, natural wood grain, and indirect warm light. And because it hangs on standard wall anchors like any mirror or framed art, it's fully renter-friendly with zero permanent modifications.
02 / Step-by-Step: Building Your Moon Mirror
Step 1: Sand and Prep Your Base
Smooth any rough factory edges on your wooden round using 80-grit sandpaper, finishing with 220-grit for a fully smooth edge. This step matters more than it seems — rough edges will catch light unevenly once the piece is backlit.
Step 2: Stain the Rim and Back
If you want dark wood tones to peek through around the edges of your finished piece, apply a walnut or espresso stain to the outer rim and back of the circle now, before adding any texture. Let it dry fully, then apply a clear matte sealer to protect the wood from ambient humidity.
Step 3: Build Your Lunar Plaster Texture
A flat circle won't read as a moon — it needs tactile dimension. Using a putty knife or gloved hands, dab and press irregular patches of lightweight joint compound across the face of the board. Leave the texture thicker near the outer edges and thinner toward the center, swirling the knife to sculpt crater-like ridges.
Resist the urge to smooth the compound out evenly. Imperfection is the entire point — a texture that is too tidy ends up looking like stucco rather than an organic lunar surface.
Step 4: Allow to Cure Fully & Sand High Peaks
Give the joint compound a full 24 hours to dry. It will lighten noticeably in color as moisture evaporates. Once cured, use a fine-grit sanding block to knock down overly sharp peaks while keeping the crater patterns intact.
Step 5: Wire the Backlighting Spacer
Attach your smaller wooden spacer block (roughly 2 inches smaller in diameter than your main board) to the exact center of the back using construction adhesive or wood screws. This creates the floating offset needed for light diffusion. Adhere your warm white LED strip along the outer perimeter of that spacer, facing outward toward the edges.
Step 6: Mount & Style the Room
Install heavy-duty D-ring hangers and picture wire rated for at least 30 pounds onto the back spacer block, and mount securely into a wall stud or drywall anchor. Dim your overhead lights, turn on your moon mirror, and balance the vignette with trailing greenery like pothos or textured linen textiles nearby.

Is a DIY moon mirror difficult to make?
No — this is considered a beginner-friendly project, since the plaster texture step is intentionally forgiving of imperfection, and the lighting wiring involves simple plug-and-play LED strip components rather than electrical work.
How much does it cost to make a glowing moon mirror?
A standard 24–30 inch DIY version typically costs $100–$150 in materials, compared to $150–$400 or more for a comparable ready-made backlit statement piece.
Can I hang this in a rental apartment?
Yes — since it mounts using standard picture-wire hanging hardware and drywall anchors the same way any heavy art piece would, it requires zero permanent structural modification.
What can I use instead of joint compound for the texture?
Lightweight textured wall plaster works as a direct substitute and is sold specifically for decorative relief art, though joint compound is generally more affordable and widely available.
Does the LED lighting need to stay on constantly?
No — most LED kits include a wireless remote or inline switch, and many run on USB or battery power so they can be switched on specifically for evening ambient lighting.
The Takeaway
My friend's "expensive-looking" moon mirror turned out to be a wood round, some joint compound, and a $20 light strip — and once I made my own, I understood exactly why she'd never bothered mentioning the price. Give yourself one weekend and a willingness to let the texture look imperfect. That's really the whole project.
