Skulls and letters are some of the most popular designs when it comes to tribal tattoo design. Individual designs are something people get a lot as well, especially those that wrap around the arms or back. Tribal can be put anywhere on the body, which is the same for any other tattoo. Depending exactly what you have in mind with your tattoo, your tribal tattoo may take a few hours to be completed. If it is a larger tattoo you may have to come back another day to have it finished.
When you decide you want a clannish tattoo, you are going to have to figure out what design you want. If you don't really know what you want this may take some time. Looking online can be one idea, or go check out some of the local designs at a studio near by. If you see something you think is cool but you want to be more creative with it, you can always add to it. Say for example you see tribal tattoo design, you could enlarge it or change just about anything in the tattoo which will make it a unique tattoo that only you have.
