Well, isn't that title a contradiction???
Crazy quilting is actually very relaxing, it's a perfect way of using of all those little cut-off pieces of fabric that you gather with all those various projects. It's also a good way of using unrepairable clothes and sheets.
You pin a little piece of fabric (red) on the middle of a block of wadding pinned to the backing fabric. Round and round you go, sewing a strip on until you've covered the entire block, then just square off.
