Wendy Wheel - Drive Band

I am trying different types of drive band on my wendy, so that I can find thr best suitable one.

First one I tried was my crochet yarn, cotton, blue color. Rumning good, but needs to be replaced super quickly. Not fun.

Second one: fishing line. Not easy to handle. Forget about it.

Third one: clothes draw string. Working ok-ish, but the pulling is too strong. Maybe good for bulky and art yarn.

Fourth one: cotton twine for cooking. So far this is what i tries. Will ad more if I changed them.

On the picture above, cotton twine works much better to make thin yarn than the drawstring.
