This pattern is interchangeable if you use another basic beanie pattern. This one is just a quick one I came up with out of the blue, feel free to make your own and follow the rest for the ears and face.
You will need some crocheting skills:
Magic Circle
sc- single crochet
dc- double crochet
slst- slip stitch

Knitting skills required:
cast on
kitchener stitch
knit
kfb
k2tg
ssk
picking up stitches

Tools Required
DPNS or Circulars Size US9 5.5mm
Tapestry Needle (there will be quite a few ends to weave in)

felt for eyes, if not you could substitute a dk weight black and white yarn and USF5 hook to emulate the cheek pattern for the eyes doing sc for the white instead of dc, and follow the pattern as written for the black.

The ears are written as how I figured out how to make them as I went, and the best I could explain how. If you have any questions please do not hesitate to message me.
