Just finished up another Hexagon Rag Rug. It's made from t shirts.
The hexagon shape measures 57 " at the widest points, and 46 " at the shorter points.Heavy and very durable.
All of the fabric was washed before used, and hosed off and air dried in the Florida sun after completion to remove any loose fibers.
I bought the t shirts at the thrift store and the proceeds of their sales go to benefit the local food bank.
