Tie-dye is a perennial favorite here. We had over 50 kids this year! It's always a lot of fun and cleanup is much easier than most people would think, so look for it every year for the foreseeable future. As I say at school visits, "When you guys stop coming to it, we'll stop doing it!" The only disappointing part for me is not getting to see the finished products. So if you came, wear your your shirt the next time you're in the library, and find me and show it to me. Some pics below, if you missed it.
