Where to get the material to make a extra large shade?

If you were interested in a rustic/farmhouse look, you could use a canvas drop cloth as the fabric. Another way to save a lot is to use tablecloths, sheets, or inexpensive curtains instead of purchasing upholstery fabric. However, even if you purchased upholstery fabric, you don’t need terribly much of it (don’t forget that the width of the fabric will give you double the length), especially if you wait for a sale and use a coupon.

Another option that I think would look look really nice would be to paint the entire shade oil rubbed bronze. Rustoleum makes a spray paint that is good on glass, plastic, metal, etc.

Good luck with your project!

l have used them in my last three houses, and couldn’t

be more pleased.

You could replace the glass at a glass shop, make it look like stained glass with glass and "lead" paints from a craft or hobby shop, or order plastic window covers like lace or some other pattern from a catalogue'
