I generally have a cup of coffee to hand when I write but on occasion, a cup of tea is better. I found this set of Novel Teas on the Writers Gifts website. It contains twenty five tea bags, each one bearing a tag with a literary quote from writers such as C S Lewis and Alice Hoffman. Writers Gifts is a British website but I found an American website called Bag Ladies Tea that sells this item too. It also comes in a smaller pouch size.
If your writerly friend is a tea drinker, this one could be an ideal gift.
