I was just looking at this pattern last night. If I were to make this kind of quilt, I would simplify it by putting all the blue patches for block A (blue leaves) in one stack and all the cream/tan patches in another. I would do the same for block B - the cream/tan leaves.
The patches would be random within the blocks, so I could make a bunch of blue leaf blocks and a bunch of cream/tan leaf blocks and just sew them together.
I don't have *any* design wall space.
I would love to see your finished quilt - I really love the indigoes.
