quite interesting and lots of historical examples.

Thank you so much for posting this! I even went to her blog search block and she had two other columns on them.

WOW, thanks for the link. What an interesting article and so many examples of what can be done with a simple shape.

I get her email and she always had something interesting.

what fun, I'm working on tumblers as a leader/ender project. Cool to see some older ones.

Thanks for sharing..
