I've been playing around with premmie patterns because work has a donation program to a local hospital, so I have been making hats anyway. For her 3 babies, I made animal themed hats.
This is a little kitty hat. The base of the hat is the same, I used the pattern here, but for the ears, I made it up myself.
R1 magic ring, sc 4
R2 2sc each
R3-5 sc each
leave a long tail and sew it on that hat
