Since this is mine, the pendant was metalstamped with my signature and then the PA Wilds brand added creating the focus.
16 gauge square and round copper wire, along with 14 gauge round were used for crimps. The smaller the number the thicker the wire when looking at the gauge size. The wrapped bead links were done in 20 gauge copper or 18 depending on hole size for 20 gauge is more suited to double wrap as seen below making some double or single wraps. I love the look of double wrapping on beads for it adds a relic element especially when oxidized.
