You'd be an easy person to knit stockings for, since if I remember your past costuming posts rightly, we're around the same height. (I'm 5'3".) I'd need your shoe size and the length of your foot from heel to toe. And maybe some general guidelines on colour?

I'd be into a simple embroidered pouch to hold my wallet when I'm doing sixth-century stuff. I don't think anything like that survives, but you could borrow a motif from the Bathilde embroidery. Calligraphy & illumination or some basic non-SCA web design might also be options?
