The Rail Fence was really not working! The beige should have had a deeper contrast value-wise with the other fabrics. This morning I took apart 32 - 6" seams and moved the one strip to the other side of the beige fabric. This looks better.
Two fifths of the blocks are complete. The other three fifths need to be made yet. Then I'll lay them out on the floor and arrange them so that there are no "L's" of dark or light fabric formed by the layout. Just offhand I can spot four. Some of the colours need to be shifted also to a more random placement. But this seems quite a bit better to me.
