I am very interested in hearing possible solutions, I have recently bought a HUGE amount of Brown Sheep Cotton Fleece for baby clothes, I hate to think I'm going to be fighting ends!!!
I would think the nail plish would make a stiff scratchy end.
I know you aren't supposed to knot when knitting but wonder if this is a case where knotting might not be a bad idea. And, making sure you always add yarn on a seam.
I'm currently working on a Vest in Cotton, haven't gone to my second skein yet (soon), it's knit in the round so now am wondering where to place the skein change to cause the least problem.
