Roc is our hostess this week and here is her fun challenge: "Hi everyone. I am really happy to be hosting this week's challenge. I'm asking you to create something with polka dots. There is something about polka dots that makes me smile. You can't be sad when you are creating them. So make them big. Make them small. Make them any size at all. See how many polka dots you can work into your art, but most of all, have fun. I can't wait to see what you come up with!"
