Ann's a quilter too, and she suggested alternating the dark and light blocks.
Whichever design I end up using, I'd always been planning on adding a couple of borders to take the quilt out to twin sized, I have some deep green and blue calico that should be enough for borders - so I went on and put blocks in that outer border of the two below, then added two more solid borders on. Now which of the three do you like better?
