absolutely LOVE the YLI hand quilting thread. It is a glazed cotton thread that goes thru the eye of the needle first time and doesn't fray!! It also doesn't knot up when quilting :)
I do find it difficult to buy locally, so i ordered some online and it was here in about 3 days.
Coats & Clarks was ok, til i tried the YLI. Hate a polyester quilting thread and C&C can be poly - so be aware
