I have a snowman panel, which I would like to finish off. Instead of several rows of border, want to limit it to one. So would like to put a row around the panel of maybe 4 patch and solid blocks, even thought of half squares?, which I may or may not use. Is there a formula for this, I thought I had seen it, but have not been able to find anything. The panel size is 34x42 1/2. Thanks for any help you can give.
