I started making a necklace but ran out of the dark, round, green beads so had to improvise. The finished product (providing I can find more dark, round, green beads will be Adventurine, S hook, dark green beads, S hook all around. The other junk on there right now is so I could see what it looked like on.
The S hooks are wire pounded a bit flat, copper permanently colored "brass" although I think it looks gold. The smaller wire is "gold" but because it was 5 bucks for a big spool, probably not real, eh? LoL.
I hope to start making more of these types of necklaces and bracelets soon.
