Pick your colors - for this pattern, I've used only about 12x15 inches of pink for paw and ear trim, 1/2 yard of purple (main) color fleece, 1/3 of a yard of cream (contrast) 1/4 of a yard of black (trim) fleece.
Project will probably take about 2 hours, maybe less.
Print and cut out all pattern pieces. The only piece that is not a full size pattern is the hat dome, but there are instructions on the pattern image for making it for your size. This hat base will have trim added to it in the second step.
Step 1: Cat hat part one
Pin ears on the inside of the hat base as shown, stitch the full length of the round edge, right sides in. Go slowly over the ears, leave bottom (head opening) open.
