Totally cute idea! That fusible piping seems really pricey to me, though. I'd probably go with a cheaper idea, like fusing THIS
to the back of the fabric, then cutting my strips - now the fabric itself is fusible, and I can wrap it around regular piping cord, or I can cut it into appliques for t-shirts and sweatshirts or wall hangings or - dare I say it - CARDS!
I've also seen baskets and rugs made with the coiled strips - you just adjust the size of the piping cord to suit your project. The ones we made "back in the day" didin't use fusible anything - we just wrapped torn strips of fabric around the cord the same way you would when covering a wreath form (another idea for the fabric there, too), then coiled them.
Thanks for the reminder - cute idea!
