Aside from the costs involved with a large tattoo, there are a couple of other things to consider, and time is one of them. A large, full back tattoo of an American eagle could take weeks worth of visits, depending on how many hours you and your artist can go in one sitting. And don't forget that more time equal more pain. So if you're a tattoo virgin, you probably want to keep it on the small side with something that can be completed in single visit that's a couple of hours or less. If you decide that life as a walking piece of art is for you, then you can always add to your collection later.
