Cut a strip of fabric thats roughly 1m long and 1.5 cm wide. It dosent really matter is the edges arent neat as they are not too important!
Paint a piece of your bangle (outside and inside) with the glue.
Stick on the end of the fabric and start wrapping.
Overlap the fabric at the edges when your wind it round, adding extra glue to the bangle and fabric your glueing on top or and continue wrapping and glueing until the whole bangle is covered.
Trim any frayed edges of fabric and coat the whole thing with a layer of PVA and leave to dry.
If you want you can sew on some pretty beads or seaquins when the glue is dry, be careful that you don't bend your needle though!
Now your bangle is ready to wear!
