Someone mentioned this on another thread and gave the url for John Flynn's site. Some of his smaller kits are affordable (to me..and not many are), e.g. a Drunkard's Path in blues....and a "Half Rail Fence" kit. I graphed it out and it looks like a standard 3-rail block, maybe just narrower pieces. What makes it a "half rail fence"? I googled it and images and pretty much all that came up were the standard rail fence designs.
