I have made at least 2 dozen of these "Flying J's (I hesitate to use the word Frisbee in case any relatives of the late inventor of the Frisbee, Mr. Morrison,  becomes one of my blog followers and I insult them by copying his design).  They are crocheted from cotton and are bendable so kiddos can stick them in their jeans pocket to have handy anytime.  They are washable and don't hurt when you whack your fingers on them!  the lighter green one glows in the dark!
