For people who would like to learn how to make a professional tattoo, this is the tutorial to watch. For making a basic arm tattoo, the subject should be seated upright in a military position. You should apply some alcohol and then some antiseptic to the area to disinfect the area and place the stencil over the area. It is suggested that the subject shave his or her arm in order to get the best effects. The tattoo stencil should be placed over the center line of the arm and align it properly, running a wet cloth over the stencil once again to make sure that it is flat. After that, you should be ready to begin tattooing a nice, even tattoo.
