While at the hardware store (Home Depot), I spotted this rope in the chain, rope and cording section.
They cut it on a machine that heat seals the ends. I added some polymer clay and loved the big, bold look of it.
This type of nylon rope comes in various thicknesses that you can have cut to any length.
I wore it to an art gathering. The ends fit snugly in the polymer clay tubes so I had no problem with it coming loose. It was fun.
