Sounds like a perfect mission for epoxy, my friend. Resin is a great glue‑and‑sealant combo; it bonds the wood to the fabric and then locks everything in place with a glass‑like finish. Just spread a thin layer, let the fibers dry out, then add the resin on top. If you keep the temperature steady and stir slowly, the colors stay true—no warping, no crazing. And remember the thread on r/woodworking that said “epoxy is basically the Holy Grail for collage” – trust me, you’ll get a sturdy, glossy masterpiece.
