The first one we did was this cute doughnut snowman (above) that I found on tipjunkie. It is super easy-you just need powdered mini-doughnuts, peanut m&ms, mini chocolate chips, and sour punch straws. You can thread them on a lollipop stick or a skewer. One thing the other leader noted, was that if the doughnuts are too dry, they will crumble when you skewer them. So if you can track down some reasonably fresh ones, like from a grocery store bakery, they will work better than the hostess ones.
Our second food craft was these edible roses. Of course, it was February, and I don't think there were any kiwis to be had! So we just used grapes and strawberries and fruit skewers. They were pretty and yummy, and in hindsight, this is probably better to do during the summer when fruit is cheaper and more plentiful! :)
The other craft we did was making our own fabric flowers, which I then glued onto headbands.
Have fun! And don't burn your fingers on the hot glue gun! Like I did. About 10 times. :)
