The photo really doesn't express how many pebbles there are. Ok, it isn't exactly a beach full, but I can tell you I spent hours on these polymer clay beach stones. I don't make entire batches of the 'same' rocks, but just like in nature will add cracks, crevices, veins and form each one individually.
Here's a tip for you...if you don't like fingerprints on your polymer clay creations or perhaps you do to make sure people know they are handmade :) smooth beads by dusting your hands and fingers with cornstarch! I'm quite finicky with my beads and personally don't like sanding or tumbling, so cornstarch does the trick for me. Also, it washes off. The pebbles with Quartz inclusions, I like tossing in a bucket of ice cold water to enhance the translucency of the Quartz.
