You can do this several ways and its really easy.
1. Contact the artist of your choice via their Instagram, Facebook or Website Shop page. Usually they respond but you must remember, these guys tattoo more than they email, so if you don't hear back, its totally normal. A lot of artists like to meet you at the show and book right there. An easy way to find the artists contact info is simply to google search their name with the word tattoo after it. For example: Oliver Peck Tattoo.
2. If the above fails... EMAIL US and we will help you get in touch with the artist you like but remember, they still may be very busy. Which leads us to the last and most sure fire way of getting an appointment...
3. COME TO THE SHOW! This is how 90% of tattoo appointments are set up. The artists love meeting you and working out your dream tattoo with you present. If they are busy thats ok and normal, you have over 400+ artists to choose from and these are the best in the world.
We hope this helps, cant wait to see you at the expo!
