In case you’re wondering how to make the top hat (the full picture is below), this isn’t exactly a pattern, but a guide…
I used half of a toilet paper roll as an insert. To figure out how big to make it, I measured the diameter of the roll, knit a swatch with my chosen yarn and used that to calculate how big of a tube to make. (For example, with diameter of 5″, at 6 stitches to an inch I would have cast on 30 st.)
I knit in the round for about 1 ½”, then decreased three stitches each round until I had 6 stitches left on the needle. I cut the yarn and pulled it through the six remaining stitches. This was the trickiest part, and getting it just right so it lies flat may take some experimentation.
Then I knit a 5 st band in seed st until, with slight stretching, I could place it around the bottom of the hat. I slip stitched that on. To complete the top hat look, I pulled up the edge of the rim on each side and “pinned” it to the side, so the brim curled up.
I then crocheted four chain st ties and attached them to the sides of the hat so they’ll go around the ears. You can see I made mine a little too long. Use your best judgment.
The bow tie I didn’t make, but I do know Asia, Jake the Cat’s mama, put the bow tie she has on a flea collar.
I know these aren’t great directions, and for the record, my patterns are much better written! But if you want to make a top hat for your cat and have enough experience to decipher what I’ve written, you should end up with the cutest little accessories for your beloved feline.
