I wanted to make Ugg "like" booties for Savannah and after searching I found this free pattern here:
The pattern was pretty good. I think my yarn was a little thicker than hers and thats why mine seem fat (just using what I had on hand). I tried to do another pair with a smaller hook and that didn't work. I do love the way they came out. They even have a lining that matches the white yarn thats on top of the boot so they are nice and soft for her.
