At some point early in my knitting career, I came upon this site. It's been in the back of my mind for a while, and I found it again today. I thought there was more information on the clocks, but I seem to have been wrong. I think I'm going to have to try this some day, especially after buying the Vogue Knitting with all the sock patterns a month or so ago. Did you see those embroidered stockings? I am a sucker for decorative embroidery.
And here is some more information on period stockings. What about a clock from a stitch dictionary? I think my Vogue Knitting Book has a couple of very decorative cable and bobble patterns that might be amazing on a stocking. Crazy, no?
