I went to a camp in MI and everyone had to bring 5" charms...that year the theme was polka dots. We had to bring as many squares as there were people. The leader took all our charms and sorted them so that we all went home with an assortment. I think there were 60 in our group, so now I have 60 polka dotted charms...and strangely enough, there were only 2 repeats!!!
