I posted a pic in the gallery crafts & dec. of a sugar ornament I made recycling a Christmas card. Please take a look.

That was beautiful. We used to do that (but not with cards) using the old Legg's eggs. I don't think they are around any more. I loved the "snow" around the outside.
Taunia, do you really make the ornament with sugar? I remember seeing something about making sugar ornaments with styrofoam. Using cards inside is a great idea! I still haven't tried your faux snow recipe, but I have it on hand (somewhere!)
