Michele, please do let me know how the tips worked out for you.
Actually, I owe YOU much thanks because your questions inspired me to try a similar design with some of the German glass that I have been struggling with. The result was very nice. If you need further help, you have my email addy. . .Just give me a shout.
On another note, I'm sure you'll dad will be proudly watching while you work. I know mine does.
Lisa, thank you and it was my pleasure!!
