Boy, I tell you. I have NO idea what I'm going to put together for a center piece.
But, for the alst Round Robin, I used this: (If anyone likes the idea, it was on Blocks Galore and is a 24" block. (All half square triangles. Get Thangles and make them PERFECT.)
I was looking at the Teddy Bear there (that's also 24") but was intimidated by it's four pages long and all the cutting and piecing and WOW! But, it's real cute.
