I like the June Taylor fray check, not sure of what it is called but not fray check but the same thing. It is on the notions wall at Joann's and much cheaper than fray check and a larger amount . Have been using it for quite some time and have never had a problem. I put it in a small bottle that is pointier at the top. I think they are either suppose to be for glue or paint, and poke a tiny pin hole in the top.
