Are you referring to the mixed? We are currently out of wire to make the nocolor in this size, which is what we use to make all anodized colors. Unfortunately there is no ETA at this time for the wire.
I have only recently started making chain flowers/hair clips, and i know it's not quite like Bills, but it works. I've been looping 2 rings through the slots of the hairclip, meeting in the + of the clip and a 3rd small ring connecting the + with the closest large ring. (It will not allow me to attach a 2.8mb image)
Excellent -- and ambitious in terms of time commitment. You're looking at from eight to twelve weeks of reasonable amounts of time (an hour or two per weekday) on the hobby, between other endeavors like school, meals, and making some medieval garb to flesh everything else out.
Hauberks are shirts -- they're just variously big, depending on whether they are eleventh-century (half sleeves) to thirteenth-century (long sleeves ending in mitts, integral coif) finishing up in the early decades of the fourteenth.
Sounds like you have the haburgeon in mind -- the sort of thing everyone thinks of for a shirt of mail; they're short sleeved, mid-thigh length. (Don't have the hem at the height of your nuts! Armour's supposed to stop you from being hurt!)
There's a shorter shirt, the vest-size byrnie. This one is strictly for Vikings and the Beowulf era.
This is the best shirt tute on the interwebz: https://web.archive.org/web/20160508055350/http://homepage.ntlworld.com/trevor.barker/farisles/guilds/armour/mail.htm -- download it so it will never disappear. It's about 4-5 pages of typescript.
