So there’s a pretty neat (and free) online program that lets you upload any photo and turn it into a crochet (or knitting) pattern for an afghan/blanket!  It’s called KnitPro 2.0, and it can be used for sc projects (one block = one sc) or even dc filet crochet projects if you upload a two-tone photo (one block = 3 sts)!  Pretty cool for a free thing.  The link to it is in my sidebar as well so you can always find it on this site!
