I wanted the look of tumbled tile without the weight or thickness, so I came up with this tutorial. Here's what you'll need: Chipboard, tissue paper, white acrylic paint or gesso, decoupage medium, stamps and inks of choice. I used CTMH stamps from "Vintage Valentine" and "Love You" sets, CTMH Vineyard Berry and Desert Sand inks, and SU! Purely Pomegranate cardstock.
Cut your chipboard the size of the image you plan to stamp (my example is 2 1/2" square). Get the chipboard damp and distress the edges by running along a countertop, tearing off small pieces, etc. (The idea is to get rid of all the obviously straight edges) Also crumple it like you do cardstock when you're distressing it. Smooth it out and let it dry. After it's dry, paint the entire front and the side edges with the paint or gesso to cover the raw chipboard.
Stamp your image onto the tissue paper, then tear around it, leaving enough extra to wrap to the back of your "tile". Spread a layer of decoupage medium onto the front and edges of the chipboard and smooth your image onto it. Spread a little more around the edges of the back and smooth the excess tissue paper around the edges and onto the back. Spread another coat of decoupage medium over the front and sides of your "tile" to seal it, and let it dry.
"Antique" your tile by dabbing desired ink color with a baby wipe, then wiping over surface of tile. Sponge more around the edges, if desired. You're done!
