[QUOTE=turbineblade;506531]Awesome responses as always! Pretty flies too. I actually have orange, wool yarn (just craft store, 100% wool stuff) that I think would work fine. I'll give that a try
The nice thing about wool/synthetic wool is it takes color from markers well. If you have white or a light color and a set of Sharpies you can have any color you want.
Sock yarn is also a good source for long, thin continuous fibers that wind into small, nicely tapered bodies.
