A really fun thing to use on a new Crazy Quilt piece is a Vintage Hankie. I've been collecting them for years and many times, I find them for just a dollar or two at flea markets, resale shops and antique shops:
This one had a rounded edges on it and was hand crocheted so I cut it and centered it at the top of this block. As you can see, I add some trim and my beloved sequins for sparkle. This one is a gift for a friend.
