Has anyone here done any portraits? I have done simple cross-stitch to crochet before and have done color blocks a million times, but would really like to do an afghan of my girls. I found a site to convert the photo in to a cross stitch pattern, but am wondering about ALL of the color changes, some are only one stitch and would like to know ... to knot or not. Most of the sites I have researched seem to be using knots, but I would really like to have a nice front and back. I could always add some fabric to the back to cover the knots, I guess. Any experience/suggestions?
