I need to get the tee shirt rug finished for a demo for guild. I started with blocks of color and ran out of light blue old tee shirts to cut up. I hope i can find the color in cotton knit at Hobby Lobby to fill in. If not, it's buying a tee shirt to cut up. Thrift shops around here cost the same as Hobby Lobby or Walmart cheap tees. For the demo I'll use a wash cloth for the rug backing but I want a finished rug to show.
