I'm finally starting to make some "guy stuff", since there've been a few guys at craft fairs and such asking for some, and I've recently made two guys' necklaces and listed them on Etsy.
Guy's Chainmaille Pendant Necklace
I made this one while watching Ironman. I don't quite know what to call the weave since I totally made it up, although it has some byzantine-like bits. It's listed here in my Etsy shop under "For Guys".
Knott Maille Guy's Necklace
This one I made less recently although I just listed it along with the other one. It's a "furby flower" with some extra rings added for tightness and decoration.
I also have some plain double-spiral chains which guys should like, but I still have to take pictures of them so I can list them. And I'm working on a guy's handflower which I hope will turn out well. I'm using 16 gauge rings (same as in these necklaces) and black leather lace.
