I ended up using these patterns:
Baby boots (ravelry)
And this is what I ended up with!
And since I also wanted to make something for the mommy, I ended up making up a beanie for her, then improvised a smaller version for her daughter so they would have matching hats!
Mommy was so happy with the gifts, she literally screamed with joy for a few minutes when she unwrapped the matching hats.. Isn’t that the best reaction you can get to a gift? :)
