My blanket doesn't look wide enough
I'm knitting a baby blanket that's supposed to be 30"x30" and done on size 7 needles. I only had size 6, so I decided to add one more cable to the pattern and cast on my stitches accordingly (pattern says cast on 120, I cast on 137). But as I'm working on it it doesn't look wide enough. Is this normal while it's still on the needles? It only looks about 2 feet wide right now, although when I stretch the free end it does look wider.
I hope that makes sense!
