I have a daughter who favors anything antique..make her pillowcases in old time rosebud prints with pale borders. Kids like whatever, sports, animals, stripes, etc. and if they get them for Christmas they can be used for a "bag" to keep their treasures in so they don't get mixed up. Men like old cars, watches, sports, farm implements, dogs, etc. Think about the person you are making them for and they will be a big hit!
