I'm impressed too! I'm new to quilting (been sewing whole life), & I don't know what size squares blocks go with what size patches, etc. I have to look at a pattern, but when the pattern says use your scraps, it makes it hard to figure out. It's amazing that a King size quilt can take up to 17 1/2 yards. People can think a handcrafted item can cost too much, but when you calculate all the costs (thread, batting, backing, etc.), and not even including the time it takes, they would be pretty surprised.
