This lovely blue necklace reminds me of the time I spend on the beach where sky is bright, water is blue and the white foam that is washed ashore with the waves. Except that the shells here are the Hill Tribe Silver beads from Thailand.
P.S. The technique I used was the same old Mugume Gane. I layered the different shades of blue on top of white, poked the holes with all kinds of thing and slided it in an angle.
