My big problems right now are A10 and B9. My workmanship isn't good and they don't lie flat. I'll go back to them later
Third row down second block in is my A11. I changed the white squares to an oblong on the opposite sides -- someone suggested that way as the easiest. Then I sewed the various parts into units to assemble into three rows. I added the white strips on the edges last. Even tho the pix in the book doesn't show it, the drawing does.
