BLANKET: Basic granny square, J hook, 22 rounds (turn after each round to avoid slanting),
3 round border: Rounds 1 & 2 as detailed on this post by Nanette Meyer Gibson: https://www.facebook.com/photo.php?fbid=10205836899869859...
I changed up round 3 so I would have enough yarn left for the hat. Round 3: 3sc, picot (chain 3, sc in first chain), 3 sc in each chain 2 space of previous round.

Hat: Basic dc beanie and just winged the flap

Flower: Details are in the the 30 minute baby hat pattern linked above. (Scroll to the bottom of the free download for the flower instructions.)
