Hex Nuts Rock!
I don't know why but I really love Hex Nuts! When I was a teenager I did my first Hex Nut Earring (which is one of my favourite earrings and I still wear it).
The other day I went to a hardware store and I found very cheap hex nut packs. I had to buy a pair! Since I bought them I've made a lot of jewlery with them (which I will upload progressively).
By the way, in my language, hex nuts are called "females" and I like to wear them as a feminist symbol: a hard and resistent female ready to rock!
