I took the leftover red yarn from making my brother's felted jester hat, and added some koolaid to try and make purple. It came out kind of burgunsy, after using 3 packets of blue koolaid, but I liked it.

I'm going to try to make my cousin another purse, though I haven't decided on a design yet. Here is a pic of the yarn:
