The wire is color coated stainless steel with a test strength of 26 lbs. They say it can be knotted, which I tried with some light yellow quartz beads and the bone color from the Harmony Trio (Bone, Lemon Quartz and Copper)
The pricing at Rings & Things is lower than the list price, but you do have to meet their minimum purchase requirements and there's a small additional cost for purchases under $50. The plus side is a full selection of trios, quantity discounts, and great customer service (plus a candy treat in the package).
By the way, if you do get a product from Rings & Things, there's a contest on this month - you only need to submit a review to enter.
There are several things I want to try, but first I decided to make a quick and fun necklace using some glass beads I'd gotten from various bead mixes. I used three strands, quartz (white) and Rhodocrosite (light pink) from the Romance set and Pink Tourmaline (a bit darker pink) from the Mystical set. I used a large sized tube crimp that all 6 strands fit into (unfortunately, I don't know the exact size) to form the loops for jump rings at the ends so I could add a clasp.
I also knotted the strands as tightly as I could against the last beads on each side and then left the rest of them bare to show off the color. Unfortunately, I had to do some adjusting and one side got a bit kinked. I'm hoping that the weight of the beads might pull out the kink, but I'm not too optimistic. Next time, I'll forgo the knots. The small pink beads between the larger glass ones are strung on just one of the three wires, by the way, to allow some additional color to show.
