I have decided I am not spending a lot of time on pressing these until, I know how they will join together. That way I can be sure seams will nest. Shoofly is a free pattern at quiltville.blogspot.com for this year's leader/ ender challenge. They finish at 4 inches, I think.
The point of a leader ender challenge is to have something ready to feed through the machine before or after whatever is the actual project. These are a little more challenging in that to keep the sets together, I feel like I have to chain the whole block. I am using small waste triangles and can't always get a set for the corners, but I think they are still charming.
