Dori, I've used Acrylic Matte Medium as the "glue" and finish coat(s) for decoupaging on wooden trays, canister sets, etc. which get handled frequently and it's held up well. I just use damp cloth to clean... The acrylic medium is supposed to be waterproof once dry, but I just use damp cloth, no damage so far. The medium can be thinned with water if you'd like....best to practice a little first.

It comes in small jars...mine is Liquitex brand from art supply store. I like the matte as it has absolutely no shine, but it's available in gloss and semigloss, too. Good luck. josh
