Now there is a title that should get your attention.

I've been playing around furling various materials just to see how some come out.

One has been punch yarn but especially after taking the strands apart....furls very nicely ...of course multiple colors can be mixed....they seem to me to be very well suited as a leg material...pick your color....seems supple ...should be durable ....and I suspect will have good motion.

Another material I think I'm going to like is 0.5mm black Stretch Magic...seems to have good qualities.

I suppose you could make some larger legs too if desired.

I,m not aware of anyone mentioning this use of furled material...of course seldom is something new.... I thought you might be interested. Try it ...be interested in your observations.
