What To Do??

OK, so we got out first block for the P2 quilt along yesterday. But here is the thing we have to come up with our own idea for the middle 12 inch square. Still not sure but I have an idea what I might do. Just have to think on it. I also still have to come up with a quilt design for the challenge that my quilt guild is doing with the RK Kona Solids charm pack that we got. Hmmmmmm.... What To Do??
