Jayne I love that layout, the quilt turned out great.
I finished piecing the first of the 4 quilts I will be able to complete with the boom 21 blocks, here is the blue and yellow top ready for the quilter. I can't remember how long ago I did the first blue and yellow block swap when I received(based on the blocks I made for this swap it was probably several years ago and probably one of my first swaps) 12 of the block so I only needed 8 more to get the size I wanted.
