Craft blog has a great feature on the work of Cathy Kasdan, who has knit an entire 1950s ensemble out of old grocery shopping bags:
The dress is all hand knit from grocery bags that were the result of actual trips to the grocery store. As soon as I told people I could use their old bags for a project they brought them in by the bag full, I received thousands! The plastic grocery bag came about in the 1950's along with futuristic optimisim about America, so I made a "typical" 1950's ensemble complete with pillbox hat and purse, not pictured. I am going to have my pieces in an art show on recycled art at the School of Art Gallery in downtown Kent along with a group of other people beginning April 19th.
