I have actually done this, but used magazine pictures. Trev's train themed room, a beautiful old steam engine pic from his magazine. My laundry room, pictures from my gardening mag. The options are endless!!!
Mod Podge switchplates. I did this and it was SUPER EASY. I did some with scrap book paper but the fabric ones turned out MUCH better. Now I have some cheetah print light switch and plug covers! - Barbara
