Thankfully I was able to find some tutorials and a video on YouTube to get me on my way. As you can see, it's not the prettiest thing in sight, but I was able to practice stringing and knotting.
I think the main problem with this necklace has to do with the knots (even though they were four strands thick). The knots are slightly smaller than the holes in the beads and doesn't keep the beads in place so they slide around a bit. I think I will cut this sucker apart and start over. And see if I can buy another strand of those turquoise beads. I bought the last strand in the store, but I'd like the necklace to be a little longer.
As for the pearl necklace? Well, I have a lot of practice ahead of me before I take it apart.
(The inspiration for this necklace came from here. I really dig the orange + turquoise together. I'm an orange-kind-of gal.)
