I looked up a set of directions to sew something on Pinterest. They were OK, but I had to sew two before I was happy with the construction. I have been sewing long enough to know that directions in commercial patterns aren't often the best way to construct the item. If I were a newbie at sewing, I'd probably have turned out a flop.
Pinterest is great if you already know how. If you are trying to learn, there are going to be a lot of failures.
FWIW, there is no place near Jacksonville where there are classes on bookbinding. Not that I'd trust. There is no miniature store, nor is there a camera place. No doll houses, no photographers. The locals think it is a big city. I know better.
