Basically, this is just a garter stitch square with an i-cord loop at the end. These cloths are very versatile, they can be used in the kitchen but they are also very nice as face cloth

You will need some worsted weight 100% cotton yarn. Peaches & Creme from Pisgah is a good choice. Use whatever leftover you have, you can mix colours if you don’t have enough of one colour. If you have only a limited amount, weight it before you start.
