It's actually a double upcycled design. The oval wrought iron links came from a length of ornamental garden chain:
It's easy to harvest big chain links for jewelry making. You just need two pairs of pliers, and a bit of gentle force in a twisting motion.
But how about those dainty Gothic black spikes? Look where they came from!
A plastic, super realistic "wrought iron" garden fence. From the dollar store! Specifically, the 99 Cents Only store. Run out and get yourself a fabulous fake fence, because here comes the DIY.
Begin with the large oval chain links. Use a jump ring to connect a little tassel to each link.
Use another jump ring to attach the link/tassel combo to the center of a necklace chain. I chose a chain with a dark gunmetal finish.
Now on to the spikes! Use wire cutters to snip the pointy bits from the garden fence.
If needed, take little snips to make them all the same length.
With a push pin, poke a starter hole near the top of the spike. Then enlarge the hole a bit, using small scissors or a skewer. It just needs to be wide enough to admit a jump ring.
Add the jump ring and connect your spike to the chain.
Now just continue building the necklace, with evenly spaced links and spikes. I used a chain long enough to go over my head, so I didn't bother with a clasp. (If you prefer a shorter look, add a clasp at the back.)
And that, my fiends, is that.
It is surprisingly light and fun to wear - heck, I'm wearing it right now. And it's not even close to Halloween.
