I do get requests for occasional projects. And not too long ago a knitter asked me to make a bunny hat for a 5/6-year-old. Since I have a big stash of yarn, I found a white yarn (no label but I think it is Lion Brand's Pound of Love, since it looks the same as my blue colored yarn that is Pound of Love that has a label). Then I needed a pink yarn for the inner part of the rabbit's ear. I had a leftover from Mandala Cake (also Lion Brand). However, that yarn was a little thinner which was perfect for my purpose. The hat was knitted from just one strand. When I was working on the ears' white part I used 2 strands, but for the pink part, I used one strand only.
Now if you would like to make the hat smaller you could 

Of course, for people that do better knitting along with the videos, I recorded my knitting. If you like to read patterns for the hat and for the ears - scroll down.

FINISHING

Sew the pink part of the ear on the top of the white ear, then sew the white ear onto the hat. Use your judgment on how you would like to have them placed on the top of the hat. When finished, weave in all the tails.
