I read on some forum, maybe this one, you can buy a liquid thingy?? to put a drop on a spool of thread to help it not be so knotty. I'm working on some hexegons. I seem to have lots of coates thread & every other spool seems to really knot up. Is there something I can use to prevent this. I have tried other brands much the same thing. I've tossed a couple spools but that gets costly. LOL. I will never stock up on sale thread again. I think it must be out dated. Does that even happen
