My friend and I frequently run to the nearby beach together and go treasure hunting (the treasure being sea glass or shells). I made this pair of necklaces, silver for her and black for me, because I wanted personalized friendship necklaces that would be unique to us. Both pieces of sea glass are light blue, which is perfect because blue is our favorite color.
The wrapping is very simple, and I just stumbled onto it when I was trying out various other wire-wrapping looks. It's basically a spiral of wire around the sea glass, and if you look closely at the pendants above, I switched the direction of the black spiral and the silver one (different slant direction) so that the necklaces would complement each other; somewhat like yin yang.
