Use the lampshade as a guide to cut out the fabric.
Start at the seam and roll the lampshade along the fabric, guiding a pencil.
Starting at the seam on the lampshade, run a line of hot glue and secure the fabric.
Continue with the glue gun at the top and bottom of the lampshade rim.
Score the excess fabric and bend over the rim, gluing with the hot glue gun.
I chose to finish the inside with gimp to leave clean edges.
And here it is:
Like these shades, but not into the crafty bit?
I'd be happy to help!
