Since you have had no one respond to you on this forum, why not try the Garden Junk forum. There are a lot of crafters there who do beautiful mosaic work and they may be able to answer your question. What you are doing, they call 'glass on glass'. Brenda

However you hang it, make sure it's supported by attaching the bottom part to something also so it doesn't swing in the wind and get trashed around. You could make a frame all around it and then using eye-hooks at each corner, suspend it in the middle. I have a couple of garden windows saved for future reference and I can't just copy them into this post (I'm also running out of time here for me to get going here). Do a search on the first page of the forum here and type in "garden windows" and you should get past posts of hanging windows because those are the pics I was looking for.

So my contractor friend told me that our windows should lift out of the frame. I read the same idea when researching windows (thinking about replacing some while the tax credit is in effect). At first when we tried, the window would shift in the frame but not quite enough to clear it. Finally got one of them out of the frame this morning! So that's a much better solution for my kitchen window I spend so many hours staring out. Lift one sash out, clean it on both sides, and reach out to clean the other sash. With microfiber cloths and Stoner's Invisible Glass! I've seen the Windex Outdoors product but feared that my hard water would leave spots after rinsing.

Are you asking about the process of how they were designed? I was really most interested in the physical installation, and your pictures made perfect sense. These are inoperable windows, right? So they're more simple than, say, double hung windows, which include mechanisms for opening /closing. You were in complete control of what size windows you installed, right? I assume they're just a standard size? On top of the glass my handyman installed wood pieces to "frame" around the glass and make it look like it's part of the window frame. This "frame" then covered over the second lip (yellow arrow). I'm not sure it the glass was epoxied or siliconed in, but I do know the wood was nailed into the side frames so none of the glass window was compromised. So you could remove the wood /remove the stained glass ... say, if you wanted to move the decorative glass to a different location, or if your exterior window were broken? One concern I have ... and maybe it's dumb. One of my fellow teachers got into BIG TROUBLE over a window a few years ago: His cheap plastic blinds were broken, and his window faces the hot-hot west. His room was roasting and his afternoon students were complaining about the glare, so -- with no help in sight from maintenance -- he took several huge pieces of thick off-the-roll bulletin board paper, and he blocked off the window, sealing it with tape on all four sides. Unfortunately, he chose black paper. A few days later his class heard a boom ... gunshot? fireworks? car backfiring? No. It was his window breaking. He had inadvertently created a greenhouse (the windows are deep set ... you can sit in them) ... and the heat built up to the point that one of his windows broke. He was in BIG TROUBLE for breaking the window and for blocking off his class' emergency exit. So, my concern ... by placing glass-over-glass, you couldn't be setting yourself up for the same situation, could you? I think no. I think the stained glass wouldn't be caulked in /it wouldn't be tight /the wood would allow for expansion or ventilation. Did this topic ever come up with either the artist who made the glass or the handiman who installed it? I'd hate to think that such a lovely (and I'm sure expensive) item could break. In this case, I wouldn't think the exterior window could break ... not from heat. He mostly designed the gingko leaf kitchen window and I made some small changes in terms of scale and placement of the center gingko leaf. That is my favorite! I've visited two stained glass places ... one focuses mainly on doors, and the door to their shop is absolutely gorgeous: Dark wood door with a full-length glass oval ... in the oval, a pink dogwood tree in full bloom. Coupled with pier glass and overhead transom ... also with dogwoods. Note: I love dogwoods. I just had to stand on the porch a while. It was the most gorgeous piece of stained glass I'd ever seen. I wish I'd asked the price, but I strongly suspect I wouldn't be willing to pay it. Nope, dumb me, I just talked about cabinet insets. Thanks for this information.
