I made this hat for Faith. The blue bird is made of sport weight and 3.25 m&m needles and measures 3 1/2 in. The yellow one is fingering and 3.0 m&m needles and measure 2 3/4 in. She really likes it and I’m happy with it too. Very quick pattern, I made both birds in one evening and the hat the same day. She wants another bird that is not attached though, so I’ll probably make her one later. She is holding one of our four kittens :)
