I took a class a looooong time ago. See if there is a glass shop near or sometimes community collages will offer courses. I would start at the library for books because they can be expensive. 🙂
Where did you collect them from? I think they are all dealer issue only, you are lucky, I would love to have any of them. The only one I do have is the secret keeper one 😀
There are only 3 people listing Wisconsin as their location in the memberlist. If they bought the pyo out of the store, you might be able to find them in the records that way.
