If I were twelve I might be able to carry this off. I should have known because it was all too easy! I took an old tee shirt, cut up the front and cut off the neckband; created a casing by folding over the cut part; then threaded a ribbon through it. It's sloppily done, and so I'm throwing it back in the "To be re-fashioned" pile. I really need to learn a little about sewing knits. Does anyone have a book or website suggestion?
