Conical Sea Shells 4 x 3.25 x .45 Blue Beautiful finishes can be achieved with mica and pearl clay, mica powders, translucent clay and other colorings. The finish can be high gloss, medium gloss and even matte finish for realism. Free Polymer Clay Project Instructions Included step by step instructions showing how to mold the largest sea shell with a color blended clay. After molding tiny ropes are extruded or rolled they are used to create the faux gold decorative coils. Gold mica powder is used to give the coils a gleaming finish. Iron-on glass or crystal jewels and the creation of tiny gold 'beads completes the rich effect. A pin back with a pendant loop makes this a dual duty beauty.
