I decided to cover my plain white desk lamp so that it matches the colour scheme of my room better.
First, I cut a piece of black cloth to size. Next, I cut up squares of scrap material and sewed the individual pieces onto the black cloth. Then, I sewed the ends of the cloth to create a sort of sleeve which could be pulled over lamp.
You don't need a sewing machine for this project. I did all the stitching by hand.
