I took the pieces of art out of the frames and stapled the fabric to it with just a regular desk stapler.
Then I Windexed (that is totally a word!) the glass and taped the fabric covered art in place.
P.S. I vowed I would never decorate with the colors my mom does. I tend to lean towards blues, greens, browns and reds. She loves the bright colors like pink, purples, lime, turquiose, and magenta. I keep telling myself I must have chosen this fabric thinking of my mom because she stays in the guest room a lot. But maybe I am becoming like my mom in my old age. Next thing I know I will collect bird figurines and put towels over my chairs to protect them from wear.
