White glass panels on plexiglass

My latest project is a doozy: 4 panels approximately 9-/2 by 22-1/2 inches that I'll be installing on track in the window well (below). The brief: Allow light and airflow while creating privacy. Make it easy to clean, incorporate the white of the window frame and as well as the rectangles. I'm using a plexiglass substrate, which is new for me and Lexel to glue the stained glass and vitreous tile. I made a tiny model of one panel in a recent class with Sonia King, teacher extraordinaire:



I can't set the exact size of the panels until I find the track system I'll use, and I can't do that until I find out how thick the plexi needs to be. Then, I've got to replace that oak window sill, which is wrecked from years of diesel soot. I've got a piece of vertical-grain douglas fir just waiting for a sunny couple of days, which I hope happens this week. The trip to Tap plastics is planned for tomorrow, and then to a hardware store for the track.

After all that, I will be all out of excuses.
