I'm thinking that if the sashing is an odd size, like template pieces are, then I'll just round it to a uniform size.
I was also thinking that I could sew a set of four blocks and sashing together to quilt and then just sew the sets of four together ala QAYG.
I'm also am more fond of hand quilting blocks than overall quilting. I've had some very fine machine quilting done on my quilts, but with something as fine as this quilt (that is hoping my version is fine!) I'd like to do the hand quilting.
