Water Bottle Cozy (Crocheted Version) fits a 500 mL water bottle and is made out of one ball of Creme de la Creme cotton with leftovers. It is a very practical and useful item to have when you are hiking, walking, biking, etc…as it gives you hands free. Especially in hot climate, I tend to freeze my water bottle so that I can enjoy cold water as it melts while the cozy absorbs the moisture. Everyone loves them. Great gift idea.
