Thanks so much for this idea! My budget is really limited and I get so annoyed watching home improvement and diy shows where the materials are SO expensive, this idea is beautiful and cheap and easily changed if you get tired of it. I don't rent but my husband never wants me to do anything permanantly weird to the house that would hurt its resale value:) So anyway, here's what I did with this idea, I'm not at all as artistic as Aliastriona, I found this template for stained glass making on the internet, blew it up and tiled it in Open Office Calc, then taped it to the outside of the window and followed the lines. It's in my little girls' bedroom, they wanted something for Valentine's decorations:
I forgot to add, it's 3 ft wide, and a little more than three feet tall, and even with three little "helpers", I did the painting part in under an hour.
