I have a Pinterest board called Handmade Jewelry Inspirations. The pieces are not arranged in any fashion other than by the date I saw and pinned them. I've opened this board and simply let the images wash over me several times when I've been trying to decide what direction to go.
I don't ever recommend copying pieces directly, especially if there is no tutorial or permission being given, but instead, just let these designs inspire you and fill your well. After the long winter we've been having, I know my well needs to be filled!
