Patt,
A heavy weight fishing line works well for the "invisible" line. However, it will stretch some. So tie it a little shorter then you want it to wind up so that it will stretch into place.

Patt,
I will definitely look you up if I ever get out your way.
Same goes for you or anyone else that comes through my area. My studio is in "Old Town Manassas" and a visit would be fun.

Tricia, thank you for posting this system, it looks very practical. I've been looking for something that will work in my (future) home studio, I will hang on to this for future reference. Thanks!
