Do you mean getting a knot-ish thing after you bind?
If so:
I get that a lot, too. I haven’t made a solution that is 100% fool-proof. I don’t know if there is one.
I have been throwing for a couple years, so I can feel when there is a knot or disturbance in the string. Just be careful when throwing. Turn your hand over immediately after the throw if you feel like it’s about to come back up. Sorry if it’s not much help.
