Grace creates

Hi, I'm making a Christmas stocking for my newest Granddaughter. I made it like a crazy quilt in assorted thin fabrics lived with Muslim. It looks really nice so far, but I don't think it is stiff enough to hold it's shape. It's about 24 inches long and sort of like an elf stocking. I want the toe part of the stocking to curl up a bit. Any idea's of a lining that is stiff enough to add to it. I was thinking of a fabric softener sheet.

Thank you all wise quilters Grace
