I was wondering whether it might be worth looking at the Shetlar stretched glass site - just for comparison of shapes and sizes between the various glass makers.
If you type in Shetlar glass into google it should come up. It's an excellent resource.
Ivo, I think of these as carnival glass because of those reasons but I don't know if they are classified as such.
I think carnival glass collectors keep stretch glass for instance as a separate category, but that might be because of the way they are made, i.e. in a different sequence of iridisation to the way carnival is made
I'm sure I read that somewhere
