Thanks, Sea Urchin! I had a lot of fun putting together the strand, and you're right, it's totally sherbet colors. The metallic luster really makes the colors pop and glow. The graduation wasn't perfect, but I think it worked out in the end, because it made the colors stand out a little bit better. This one is intended as a gift, so I haven't gotten neck shots before it was set on its way...
I got these particular pearls at Care Ehret as a set of multicolor strands, which I imagine are reasonably easy to get many places. The fun is in sorting and sorting and then arranging. If you have OCD tendencies like me, it can be a little aggravating (in a good way).
I'm thinking of getting a few more similar strands from PP to make into a longer rope (for myself). The looped graduation makes a really neat effect. Good luck and post your results!
