A friend knows what makes their friend smile. Knowing your friend's needs and wants makes it easy to find the perfect Christmas gift. Your friend has already shared her interests with you; choose a gift related to her favorite pastime or hobby and you can't go wrong. Customizing a scrapbook or photograph album complete with mementos of your times together, buying that snuggly sweater she has long admired, or picking up the latest title by her favorite author - personally inscribed, of course - are all simple but loving gifts.
