In this video you see my original rug made from sheets we call the "monarch" rug, and the rug I made from its leftovers and another animal print sheet.
Toothbrush rug making is a folk craft version of naalbinding which produces beautiful artistic results which you not only CAN walk on, but which are made for that explicit purpose.
They're also a great way to recycle, as the raw materials are usually scraps of clothing / linens, old plastic bags or hosiery, etc.
