Maybe a gift voucher from a local wool supplier?
If you want to make her something, what about a couple of felt play balls for her pets? You could put a sort of jingle bell in the middle, in a small plastic container, like something from a Kinder surprise egg, and felt wool around it?
If you can't felt, don't panic! You can felt knitted wool in a washing machine! I've seen it done in books, although never tried myself -
