I have made similar necklaces to this, but not for a while, and fortunately I remembered that I needed to start in the MIDDLE as I progressed with the stringing of this piece. It's in very springy, almost Easter egg colors. It's the kind that just slips over your head and no fiddling with clasps or anything. The good thing about that is that you don't have to worry about fidgeting, but the drawback is that it is not adjustable.
In making this I also did something I don't normally do...I left enough rings to make them into earrings and will have my hand at that later on today.
The finished necklace is about 75 cm in length, making it about 30 inches. It does match most of my monocolor summery wardrobe because it has all those colors in it.
I realize it should have been shown with the focal piece at the bottom, but I wanted the entire piece to show so I left it this way.
