Your husband sounds like a hoot!
I'm teaching my boyfriend to knit (you know, since I'm such a pro, knitting for two whole months now) and he keeps splitting the yarn and ending up with an extra stitch. So also check for that.
Maybe the current square can become an ankle blanket, then you can knit a leg blanket, knee blanket, connect all of those to a hip bone blanket...and end up with a person-sized blanket. :mrgreen:
