You will need, apart from some nice sea glass pieces, wire about 1 mm thick. I use zinc-coated steel one (it’s cheaper), but copper one will do too. Not the copper-coated.
Wire cutter, pilers, solder (lead-free), some stained glass flux. Soldering iron better less powerful and with smaller tip than those for stained glass making. About 60 wt will be ok.
Put some flux on the wire and cover it with solder. The rest of process is on the pictures – I believe they’re quite self-explainatory. If you haven’t done wire wrap before, prepare yourself for not getting the result from first try. But practice makes perfect 🙂
Don’t forget in the end to wash nicely ready item, and then file/polish away any imperfections. Or just buy mine 🙂
