Thank you for your replies. I usually don't use fray block on quilts; however I am making a memory quilt from my nephew's jeans and someone here suggested using fray block because denim tends to fray.... so I don't want my quilt to fall apart so I want to use fray block. KalamaQuilts: Does the clean nail polish dry stiff and hard or is it pliable? June Taylor's is very nice, but the bottles are pretty small for how much I am going to be using. Sewbeadit: I have only seen the June Tailor fray block in one size. Have you seen this in more than 1 size?Overstock has a good price, but I just wish I could get a bigger bottle
