Are they they left over "safety" ring from when you open a bottle of water/soda/milk carton?
the ring off of a 20oz bottle????????
Yup, soda bottle type ring. Still, kinda cool looking.
Wow Crafty, awfully specific! :) They are indeed the safety rings from a glass milk jug...the ones in this post: http://upcycledstuff.blogspot.com/2012/04/why-i-love-my-smaller-green-grocer.html They are huge too, skimming my shoulders when I wear them!
