I'm not sure that a cross stitch pattern would work as a knitted motif. The stitches in cross stitch are all perfectly square, whereas knitted stitches are not - their height is greater than their width, not by much I grant you, but when that elongation is multiplied over the entire motif, the finished image would be distorted. I've never tried it, so I can't be certain just how much of a distortion there would be - maybe not enough to really notice, but I don't think I'd want to put all that work in only to be disappointed
