You can choose from one of the shop’s predrawn designs (called flash), draw your own (or have a friend do it), or have the artist design a custom piece. The choice is totally up to you. Just keep a few things in mind.
The vast majority of flash is purchased from tatoo supply companies by shops all over the world. If you get one of these designs, don’t be surprised if you see it on everybody and his brother. It’s not the way to go if you want something “different”. If you bring in a drawing for the tatooist to duplicate, make sure (by looking at his portfolio) that he’s capable of it. Also, make sure that whatever design you choose should be an appropriate shape and size for the body part it’s on. Take your tatooist’s advice. Remember, he does this for a living, and most likely knows better than you what makes a good tatoo. If you don’t trust him enough to listen to his input, he shouldn’t be tatooing you.
Ideally, though, you’ll like the artist’s style enough to have him custom design a piece especially for you. This usually requires a small, nonrefundable deposit to be put down to let the artist know you’re serious and get him started on the drawing. You should discuss what kind of imagery you want, the approximate size, the placement, and your budget. Then the tatooist will take some time (a few days or weeks, depending on the complexity of the design and his workload) to draw it up for you. Once you’ve come to an agreement on the drawing, the artist should give you a rough price quote for the work and then make an appointment for you to get your new tatoo. Get plenty of rest the night before (no partying), eat a good meal a couple of hours before the appointment, show up on time, and bring enough money for the tatoo and a reasonable tip. Then, just relax and leave everything up to the nice tatooist. If you’ve done your homework and picked a skillful, talented artist, he’ll take good care of you. Also, follow the aftercare instructions you’re given to the letter. Don’t follow anyone’s advice but your tatooist. This final, and hugely important, detail will ensure a finished product you can be proud of.
