On the second try, I was able to whip up these quick booties for our new baby J.
I used the tutorial and pattern here. As printed it turned out to just barely squueze onto his 4 month feet, so I'd say the would fit a baby 3 months and under. I enlarged it 115% and they fit perfectly. They are two layers of fleece and have double elastic bands so they ACTUALLY STAY ON!!! So simple to do... I'll be trying to figure out a 6-12 mo size! and maybe even larger for E!
this tutorial for my neice... hope they fit!
