Hey, lads and ladies. I'm a semi-newbie crochet...er. I was wondering if anyone has tried free-form crochet. There was a needlework gallery at my library recently and somebody had put up a crocheted wall hanging of a 3-D face. I was curious if this was best done with yarn or string and if you have to "pad" the back or stiffen the string to make the images stand out. Any ideas?
