What are you wearing?

I have been substitute teaching a lot lately! It's fun and when I grow up I think I want to be a teacher. The other day I wore my new homemade broach on a brown shirt. When I walked out of my room dressed and ready to go my kids looked at me and said mom what's that? I asked them what. They said that thing on your shirt. So I told them my new broach and they cracked up asking again it's a what? Anyways you just cut circles, sew an X in the middle and attach a button...I liked it.
