Every year we decorate halloween koozies to use for the party and let the guest take them home as party favors. The last two years we bought the foam koozies and decorated them with paint, glitter, plastic spiders, etc., using clever halloween sayings or quotes from horror movies. By the end of the evening the paint had worn off, or whatever was hot glued on had fallen off. This year we bought the collapsible koozies, printed up pictures and sayings from the printer, and put them on iron-on transfer paper. Then we got the iron out and went to town ironing on all the pictures that we had printed up. I must say that they look like they were professionally done at a fraction of the cost. I found the collapsible koozies online and at a very reasonable price, just .60 a piece. Here's the link:
Blank Collapsible Koozie/Can Holder - NO MINIMUMS! You can also order the iron-on transfers from HP.com. I bought three packs, but they gave me one for free, and took only two days to receive by mail. Attached are some pics of some of the koozies we did.
