Vintage Fabric Rag Rug Yarn Weaving 21 yards continuous finished folded edges

This is one continuous piece and has been hand folded, so it’s not right edges. Each strip has been sewn together to make it one continuous piece. A lot of work went into this. I enrolled it to Measure how long it is and then re-rolled it just the unrolling and the re-rolling was a lot of work so I can just imagine all the work that went into making this
