What needle should you use to colour tribal tattoos?
This is totally dependent on the size of the piece that you are doing, the bigger the piece, the bigger the needle set. Typically, I like to fill tribal with a round shader as opposed to a mag. In my opinion you get a tighter grouping without having to really work at it, and for the most part, I hit the edges usually with a 15RS, and then will switch over to a 25RS for the middle fill. Most artists, including myself, will have a machine set up solely for tribal. Having a machine set up for a nice long stroke will give you the optimal results for tribal rather than trying to do it with a typical machine set up for general shade.
