I just bought new sheets at Christmastime (thanks Grandma!) and it killed me to throw out the thick, plastic, zippered cases they came in. So what is a mom to do? Upcycle!
I simply sewed a strap to the top (that's the black thing you see). The strap was a thick piece of ribbon. It's as simple as that.
There are pouches in the front and back where the labels for the sheets went. You can stick a picture, label, or card (as seen here) in those pouches and fill your new bag with whatever you want. I chose to hold my handmade cards in this one. But I thought that yarn would be a great thing for these to hold. You could even punch a large eyelet trough the bag and string the yarn through to keep control of the yarn for a project you are working on!
