I made Monika and Catherine necklaces from some of the sea urchin spines I collected in Malibu. This is Catherine's necklace. Yes, I did have to twist the spines from the urchin's shell and scrape a little tissue from the ends, but it's not like I didn't clean them. The last time I was home, I plucked another bagful of spines from my urchins because I'm formulating some plans for earrings and more necklaces. And when Catherine and I head out to California in April...oh, you know we'll be collecting more gifts from the sea and turning them into wearable treasures. Guaranteed.
