My workmate asked me to make a hat for his sister's newborn baby. So I found a free crochet pattern for a baby hat, for age 0-3 months, picked out some yarn and an appropriate sized hook (as stated in the pattern) and set about making it. I was watching a movie at the time and not really paying a lot of attention to the hat as it grew - although I did follow the pattern to the letter.
The stupid thing turned out to be a bit big even for me! If I saw a newborn baby with a head that would fit in this hat, I would run away very fast.
I'll keep it and turn it into a nice cloche type hat and add some flowers or something to embellish it, but it's still a pain because now I'm going to have to start over and make another baby hat. I can't even freehand it because I have no idea how big a baby's head is!
