I want to do a faux-stained/etched glass on some of my windows - cut contact paper to size, apply to inside of window, draw on with paint pens and sharpies. I did this in the shower window in my last house and LOVED it!
This was my most popular card at any class I've ever had. I almost thought that it was too silly (guess that speaks volumes for my customer base, LOL). Obviously they need a sense of humor to keep me as a demonstrator.
