Thank you for your suggestion, otherwise it wouldn't have occured to me. But after having checked our library, they don't have that book. However, they did have another which offered not "32 hats" like yours, but "31", and it's on hold now!
I'm afraid I don't know how to crochet yet, but the pattern you linked to was the perfect example of what I was looking for, only in a knit form. Thanks again.
