a great tip i discovered!
was having a very hard time threading my size 12 clover quilting needles. I had asked in another thread if the 10 eyes were bigger but I like using 12.the king tut variegated thread is thicker and would not work with my expensive bohn needle threader I love so much.
Also broke 2 of the cheap ones from walmart, so this morn I tried dipping the end in fray check and letting it dry and was able to thread 12 with no threader!!!!!
