KnitPro: turn your photos into knitting patterns
Make your own knitting patterns from your own pictures. This works well from intarsia projects. Alternatively, if you want to do textured projects, you can replace a colour with a particular stitch. You can also generate patterns for needlepoint, cross stitch and crochet.
