The knit charts can be done by hand or by machine, and the crochet
charts are a square format that can be used for other things that take
a square grid, like beading or cross stitch.
If you or anyone you know is looking for Star Wars crochet or knit
charts, these are intarsia/color charts and aren't for the faint of
heart because of all the ends you'll need to weave in, but they do
look GREAT when done.
Feel free to post the URL to other sites if you know of other people
who are looking.
