Hey, I'm thinking these might make interesting tree ornaments and other hanging ornaments, if you join the circles together with small pieces of ribbon. Would that work? Maybe smaller versions, using mushroom can lids? Or even jar lids?

I used to like covering used cans with fabric and making pen and pencil holders. I did it with linen, batting and lace once! But only once. Too complicated.

Good luck at the bazaars! Sounds like a whole lotta fun!
