I plan on crocheting a bunch of small prizes and giving each member of the winning team a prize.
I also want to lay out a bunch of pieces of yarn and try to teach everyone how to finger crochet (since teaching how to crochet with a hook takes a lot of time, individual attention, and crochet hooks).
I would like to bring some kind of food as well, but haven't yet thought of anything that connects well with crochet. I could possibly bring cookies shaped like crochet hooks (basically candy canes) or make a cake that somehow connects. My presentation is May 25th, however, so I still have some time to work out the details.
