Great news! After much deliberation, and many broken-slash-failed pieces of stained glass, I decided to slightly reconfigure my design. My main purpose for doing this? The blue glass is still on back order. For me to complete my piece without more delays, I figured I'd have to push forward at some point and work with what I have. Here's what I ended up with...
Ta-daaaaaaaa! Here it is. I still love the flow of the design, even though it's slightly different from my original sketch. And not all of the dark pieces above are black: Most are the transparent purple/magenta color. I'm hoping that when it's back-lit, the colors will really shine.
Onto my little subject title about delays. I noticed today that I don't have enough copper foil to complete my goal by this Sunday. Faaaaaaaaaaaaail. As soon as I realized that, I ordered more 1/4" 1mm foil from Warner Stained Glass. Alas, it's a Friday before a holiday weekend. I sincerely doubt that I'll start foiling again until maybe Tuesday. I made great progress today though!
