I made my husband a hat and it turned out to be just a little too big around. I thought I had measured it correctly but it's a little loose and he wants it to fit snugly. Is there anything I can do to fix it?? I originally knit it flat and seamed it. I was thinking of just going over the seam a little and seeing if that would help. I don't want to start over but I'm not sure how best to fix it!

any advce would be really appreciated!
thanks
