1 - tea towel
Elastic
thread
Heavy cord for hanging (macramé - or tight crocheted chain works well)
Take tea towel and attach elastic to the backside at about 2" from top and 2" from bottom of tea towel. (Make sure you stretch it to the length of the towel so whenever you let go it squeezes towel) Then while inside out sew the two sides of the towel length wise from top to bottom, and then turn the bag right side out. All you need to do now is attach the cord and hang - fill with plastic shopping bags. Works great - reduce, reuse, recycle!!
This is a great to use as a shower gift, I put money inside them and wrap whenever I have nothing else to give. Great for couples moving into a new home, and cheap Christmas gifts for relatives.
