DIY NECKLACE #2

I went rummaging around Bunnings (my local hardware store) and I fell in love with two aisles; plumbing fittings and wall fixtures. I got a little excited and made these two necklaces. At this point, I favour the silver one. However, it does weigh about a kilo and a half...

To make the silver one, I used:
 - a length of flexible irrigation tubing
 - 20 x 20mm nuts
 - 12 x 30mm nuts
 - 3 x 45mm nuts
 - plumbing pipe fastener (to hold the necklace together at the back)

And the gold one:
 - 5 meters cheap gold chain from a craft store
 - 2 x "some random piece of plumbing pipe thing"
 - 1 x "some slightly larger piece of plumbing pipe thing"
 - excuse the vague there, I don't know the right name for those things..
