Haven't a clue, sorry - I ended up cheating and buying a stocking cap from Jas Townsend... and needing to shrink it. (It practically felted itself in the process. Oops. Oh, the trouble you have when you have a smaller than average hat size!)

Just popping in to say I haven't seen you around in a while and good luck with your project, when you do settle on what stitch type to use. *hugs* (Also, don't forget to post pics of the finished article. :D )
