Great thread.
It is interesting that several people are unhappy with the same products. I have revised my personal wishlist for next years sewing show.
Thimbles were mentioned by several people. The best thimble I ever had (yes had, I lost it), was a handmade finger sock with a leather pad. It was great. It did was not too tight, breathed (no sweaty fingertip) and worked really well for me.
I guess there needs to be another thread (maybe there is already) of the best thing you bought at a show.
I treat sewing/quilting books/magazines the same way I do cooking/recipe ones. If I get one great tip or project (or recipe) out of a magazine or book I am happy.
