cjsews, thanks. I figured I could do that but was wondering if there was an "appropriate" proportion. I had thought that for a 12" finished block, that perhaps the first row and last row would be 3 1/2" and the middle would be 5"?
And, thanks dunster for the link. That is one wild churn dash! I love it, but wouldn't know where to start. I have problems wrapping scrappy around my brain.
