A mosaic frame or mosaic substrate is the base surface that you build your mosaic on. It’s the foundation that holds all the materials — glass, tile, beads, china, or other treasures — in place once they’re glued and grouted.

Our mosaic frames are beautifully cut, ready-to-use wood bases designed specifically for mosaic art. They come in different shapes and sizes — from classic frames to decorative designs — and provide a sturdy, smooth surface for your creative vision to come to life.
