sewlo, I love them. Talk about looking like stain glass, these do. Are all your strips the same size? I have never like these type of blocks because the distraction in the center because all the strips do match, but yours is different. It must be because you have added the black sashing between each block. I have all kinds of small strip, I am going to use this technique for make quilts for a large picture window.
Did you quilt them and how did you hange them?
