I've made these paper bird necklaces from aged, water-colored parchment paper and beveled glass. The small ones are about 1 1/2" square and the large one (bottom) is 1 1/2" x 2". Lead-free solder is used on all my charms. These come with ball chains that can easily be changed out for a different style if you have a favorite chain at home.
