Anyone tried the paper napkin and decoupoge on wood trivet, ?

Yes! It comes out great, I can't wait to see yours!

Not on wood, but I have done it on ceramics and it pretty cool and relatively fast. I buy holiday napkins, cut the design out that I want and deco it onto the outside of candy dishes, etc.

Mod Podge works, too. But I would seal it after you do it. Mod Podge first. Then put the napkin on. Mod Podge again. Let it dry and seal.

absolutely but I would paint it white first so that the true colors come through.

No, but ny closest friend, just befoe she died last year shiwed me how to make Christmas ornaments and this year I am making a ton of them for our "Christmas in July" celebration. I was amazed at how beautiful they are and they match my paper plates and paper cups. They make a wonderful gift for your guests to take home as a memory. The cost is minimal!!
