I think this is a great idea. I saw on another thread where SewingSew (a member of this board) does the same thing.

I don't use anything and have never had any cotton thread unwind. The only thread I've ever had an issue with is filament poly threads because they have no texture to grip to themselves.

what great ideas! I love the painter's tape and pony tail elastic idea, I think I'll adopt one of those. I recall someone on this board mentioning at one time that they used condoms (unlubricated of course), although I think that would get a bit expensive.

A section of panty hose works well

Pull off about a foot of thread - don't cut it - make a loop larger than the diameter of your cone of thread. Holding the loop between your thumb and forefinger and using your other hand make 3 twists in the loop then put the loop over the thread cone, pull the thread tight with the end of the thread. To use your thread again you should be able to tug the thread and the knot will loosen up.
