Adorable, right? There's a great little tutorial including pattern there, but because I never follow directions, I decided to go for it on my own.
The originals were made of felt, but I made mine out of super soft white fleece. I just drew it out straight on the fabric and cut away. For the accent colors (the boys each wanted orange and I decided on red for my niece), I used some left over felt from our Angry Birds Backpack Pals (found here).
I used some embroidery thread for the eyes and mouth and cut a tiny little triangle of felt for the nose. After I was done embellishing the face, I sewed the color on the ears. Next, I pinned the ears in place and sewed the whole thing together on my machine. I left just about 1/8 inch seam allowance.
At the last minute, I decided to add a couple of cute little carrots for the kids to play with.
