My aunt recently visited Chapel Hill, NC and saw an art exhibit called Scrapel Hill.
It contains works involving cast off materials. I'm sorry I don't have the artists' names for you.
The above quilt is comprised of plastic bag yo-yos.
This quilt is all socks. A great idea for all those lonesome socks missing a partner!
I bet it would be warm too.
If you are in the area, I believe it goes until July 22, 2012.
