I followed instructions from Bonnie Hunter's website
www.quiltville.com which included a full 1 inch seam allowance. Believe she called the pattern Raggedy Bricks (it uses squares and rectangles). I used homespuns one side, 100% cottons on the other and cotton batting cut 1 " smaller all around with the X sewn diagonally both directions. It is still a WIP but I would think the 1" seam would be "fluffier" after clipping than a 1/2" seam, though heavier as well. We shall see. I like the idea of using flannel same size as the others pieces instead of batting cut smaller and will try that if there is a next time!
