- Sew the fabric tube, right sides together. Make it at least an inch longer than it needs to be.
- Fold the top ½" to the inside of the tube and cut diagonally across one corner forming a cut-out diamond notch
- Insert the shorter leg of the bobby pin into the top of the tube (the core) and the longer leg of the bobby pin in through the cut-out notch. Start turning.
- Once the tube is fully turned, chop off the dodgy end with the notch.
