I just finished a long patchwork squares (rectangles) skirt using some of these...3 rows of 9 - a light, a medium, a dark alternating around each row and forming a diagonal pattern. I just put a casing for elastic at the top and will let her determine the depth of the hem at the bottom. She gave me several of those sample books, saying it didn't look like she would ever use them. So I asked what she had planned to do with them and she mentioned wanting to make a skirt, so I did.
I also have used them for bags, wallets, checkbook covers, etc.
Am wanting to make something fancy with the silk drapery fabrics. They are gorgeous!
