I was inspired by the now popular animal hats that have ears and such and decided to crochet my own. Just use any hat pattern then crochet the ears separately and sew on.
Ears:
Ch 13, Ch 1 and turn.
Repeat for 2 rows.
On 4th row dec then sc in middle until last 2 sts and dec again.
Repeat for next 3 rows.
Then sc until you have only one st in the row. This is the tip of the ear.
To make larger you can sc all the way around the outer sts.
Tufts:
For the ear tufts I used a lighter. Wrap the yarn around the light about 15-20 times depending how much tuft you want. Then tie off one side with separate piece of yarn. Take off lighter and cut the round of yarn. Take the part you tied it and tie that into your remaining loop. Fasten off. You may trim down the tuft to make it more realistic.
