Fold in half and join the sides to form the back of the hat.

To sew, count 3 stitches from the collar of the coat, only in the area delimited between the white lines in the image below.

Sew 2 stitches from the base of the hat to each stitch from the base of the coat, since there are more stitches at the base of the hat than at the collar of the coat.

Put the ears in the holes in the hood, and your mascot will be ready for a cold and rainy day (which I honestly love for crocheting while drinking a hot tea).
