I'd like to start crocheting this year. I have wool. I have a crochet hook. I've been looking on You Tube and am struggling to follow even the basic tutorials :-( So I've decided to 'go it alone' ha ha. If I cast on 100 stitches and then just repeat that row again and again will it eventually turn into a big square which can become a baby blanket? Thank you for helping me with this :-)
