If you like this, go to Laurie Oladele's videos to let her know! https://www.youtube.com/watch?v=APxClMlIPCs . If you are new to rag rugs, I left out her beginning videos that show how to make and extend fabric yarn. I pieced together the parts that helped me most.
Oladele shows us how to start a four-strand braided rug (using the 3-strand start), use the Over-Under-Over (OUO) pattern for plaiting, turn corners, and how to finish a braided rag rug. This is a great way to upcycle old shirts and bed sheets.
