1.) Each quilt is "as built". The number of different blocks changes as the reversed blocks use the same pieces, it's just which edge gets attached to which other edge. Hence the map is really good only for one quilt unless you are very conscientious about how you assemble the blocks. With YBR, that would drive me crazy. It's easier to do the final design at the end.
2.) I am impressed that you realized that there are only 5 different block patterns as one of the 3 is not reversable.
3.) I'll have to see about getting my layout map from one computer to another so you can see how I did it.
