Scrap fabric or new fabric Ribbon Lace Old clothing Old house linen Handkerchiefs, etc.
Glue the starting end, then every few wraps of the fabric with the first way, then glue the finishing end. If wrapping the entirety, roll glue over the bangle first, then glue at the join of the fabric. Add a length of ribbon or scrap fabric over the join, to neaten, and glue in place.
