Is it possible to donate to Habitat for Humanity or something similar?

Paint glass in a stained glass type pattern, hang as room divider.

Hinge several together, for the space you need, add a stable base if necessary, use as a folding screen to define space.

Make a display table, add 3-4 inch deep sides, hinged, add solid bottom and legs. Display your favorites items securely.

I was thinking you could make a headboard for your bed by replacing the glass with plywood then covering with padding and a pretty fabric.

I have seen smaller windows decorated with a windowbox and some silk flowers then hung on the wall as decoration.

Get a bunch of windows together and make a hothouse or greenhouse for growing/starting plants.

I’ve listened to NPR interviews within the last six months that explain how to do this easily with explosive results. It could likely be googled.

There’s a restaurant near my apartment (called M. Henry)that does the window pane room divider thing beautifully. They painted the frames, screwed in eye-hooks, then hung them from two chains by S-hook.

(Tiny pics but you get the idea.)

I have always loved their windows and think of them every time I see a discarded old window in an alley.

I can imagine some lovely wall hangings if you decoupage dried foliage, as one example, to the back side of the glass, and hang on the wall. These could also be used to make light boxes, with a light source underneath, for tracing art and patterns. What about cutting away the upper center of a hollow core interior door and using the clear window frame in that space to let light pass through between rooms more easily? Could they be installed onto the front of a bookcase as glass doors? Hinged to the wall against another window to provide a shutter-like extra layer of insulation (that also can be decorative or light-diffusing, maybe by using frosted glass spray or other paint). Perhaps attach the glass directly to the wall (if its beveled and can be used without the frame), using mirror mountings, as a backsplash, or way of adding color in a rental when you can’t paint walls. The wooden frame still around the window helps make them much more versatile for re-use.

I would use them as frames for anything from photos to posters and hang them on the walls. Silly idea?

Make a compost bin and use the windows as covers to speed up the composting!

Donate them to a local art school, a lot of artists (or budding ones) seem to think it’s a good and easy (not really so) thing to paint on them, and they always need stuff like that, especially in underfunded highschool and college art programs.

Artists and crafters love these windows. Our town has tons of these crafters that use the old pane windows in their art projects, painting murals to “stained-glass” patterns in them.

Don’t throw them. List them on Craigslist.org free section and you will have people fighting over them…
