These are made to order. It was good to dig out the rubber again and have a play.(Does that sound slightly sordid?)
This one is simple. Cut a length of tube on the curve.
Cut bottom edge and wash inside and out.
When it's dry, stitch a casing along with the sewing machine.
Then with scissors carefully cut fringing.
Thread chain through the casing to the length you want.
This one is a bit more complicated with tassels and jump rings but not too tricky because I'm not very good with jewellery stuff - pliers and the like - and I managed to make it!
