Are you in need of a cold frame? Old windows are great for that , depends on how handy you are as to whether you build wooden sides or frames for your windows to create a glass box.

I've seen so many pretty shadow boxes and decorated hanging windows, it's really dependent on what you like. There are many ways to use old windows.

I just watched a show last weekend in which an old feed silo was converted into a bar. They used old windows with colored gels over the glass and then backlit to draw the eyes up to the top. A really colorful way to bring light to a dark space. That would not hold up well in weather, I imagine.

Thank you! Maybe doing something like coloring the glass and making a mosaic-type thing? Or if I get too lazy a cold frame would be my choice!

Oh my neighbor and I did some beautiful old windows. Use pieces of colored glass and glue them on in design or just randomly. Put hooks on the top edge and hang with Chain from the trees, porches, etc

Ithink I have a picture of one

I got the idea here from a post that had some really pretty ones.

Here's one we did.

Can paint on panes or put mirror behind them & hang in area where sun won't hit it & heat up & start a fire. If you aren't very handy might find some butterfly or bird stencils to apply to the glass. Even simple flowers on the panes would be pretty tape coloring book flower to other side of glass & use outline of flower & fill in with paint ,a little shading & some dots in center of flower & would look pretty real.

I love these ideas. I'm not good at painting but could certainly use sunnyca's idea of using a coloring book picture. That along with a few glass gems would really brighten up an old window.
