1.  Cut a piece of yarn that will be long enough to sew around three sides of the dish rags.  Hold the two cloths exactly together.  Tie one end of the yarn through the two cloths at one of the corners.  Lace the yarn in and out around three side of both cloths to sew them together.  Tie off the yarn and trim off any extra yarn.  To make the lacing easier, tape the end of the yarn to make it stiff.  You could also dip the end of the yarn in glue and let it dry to stiffen it. 

2.  Cut a long piece of yarn. Tie one end to each side of the open end of the bag to make a hanger.  Collect some soft old undershirts and cut them into squares to use as a filler to show what this bag is for.
