I started with 10" squares for stack and whack. I wanted a finished 8" block with internal squares of 3" and 4". I made a 3" block first and decided it was too small - it got swallowed up by the outer edge. With a bit more research I decided a 4" and 5" internal square would be better.
I must say, I really like how they look. I made about ten of them and began to doubt - would they clash? How would it all go together? I plugged along until I finished the 30 blocks I needed. I figured I needed to see it all together and then modify as necessary. It is a boisterous colorful combination! My baby quilts tend to be bright - this thing is certainly not subtle. But I like it. The top is sewn together and I purchased backing over the weekend (not what I expected, but I like it!). The quilt is speaking to me about quilting - it wants curves and a walking foot. I had thought I'd be doing freemotion on it, but I guess not!
