I agree with everything you said except for the cat beret part, don't knock it til you've tried it. which I have.
Thanks so much!
The patterns are from a book by Sara Thomas called Cats in Hats: 30 Knit and Crochet Hat Patterns for Your Kitty
Then we absolutely need to see more examples.
edit: Actually, I seem to have found the exact book (in English) - https://www.amazon.com/Cats-Hats-Crochet-Patterns-Kitty/dp/0762456639
It came from this book!
Thanks! =D
I was a bit worried it was for knitters, so I went hunting, and it has both crochet and knit! =D
