Haven't got any pics just yet! will get some next time I can get my mate to get a pic! In the meantime, it's an olive green woolen ruana style cloak. It's about knee length plus a little and has a loose fitting hood. It's amazingly warm. It's basically a wearable blanket!
I hadn't considered making one, but I'll keep it in mind. I certainly don't have the mental bandwidth at the moment, but I imagine it's much cheaper than buying one.
