Ok, I think I have it figured out. My quilt will have four blocks across and four blocks down. First row, Make the the complete blocks but leave the right petal off. When you join the blocks, the left side petal with fit into the right space.
Second row, make the middle of the block and two bottom petals, the two side and two top pieces will be left blank as they will fit to the top row and side blocks.
you can do this either way. Work each row and add the petals as needed. I will do the side next.
