I have 2 Roxanne thimbles, I like them, but I have found that I bought the 2nd a little tight. I have a thimble my mother bought for me 39 years ago and I can't find another like it, it is a regular thimble that looks like a small can openercut 1/2 of the top and bent it up to allow your long fingernail to come thru, has anyone seen this?
