This pin is made from polymer clay in blue, red, turquoise, and a semitranslucent white. The individual motifs remind me of cells in culture or on a microscope slide. It would be an excellent gift for a cell biologist or other microscopy enthusiast.
This pin has a standard bar-style pin backing.
All of my polymer clay jewelry, beads as well as other shapes, is made by hand, without molds or commercial canes of any kind.
