I spent this weekend cleaning out the guest bedroom closet junk closet. Oddly enough, the little project below helped me maintain my sanity. And since tomorrow is February 1st, let the Valentine's Decorating commence!
First, locate all those Tar-jay bags you've been collecting to recycle or reuse. While you're at it, cut out a nice sized square from an cardboard box you have lying around and make your heart "frame." I made my frame about 1" thick. Next, layer up about 4 strips cut from the plastic bag and double knot around your heart frame -- just eyeball length and width of the strips to get the look you want. Keep stripping, layering, knotting all the way around the heart.
Disclaimer: If I knew up front how long this would take, I probably would have made that heart a lot smaller.
