What I do is take the average of the five tattoos and present the host with a free tattoo of that value,or a discount of that amount on their tattoo work. Some hosts don't get tattooed at all and in that case, I give them the average amount I did in cash.
I do parties only Fridays Saturdays or Sundays. And I am sometimes available throughout the week for private sessions with a minimum of a hundred dollars per visit with a client at their house.
Many of my clients that host parties get the more serious pieces (sleaves, backpieces, large pieces) and having a party every month or so is a way they can get their tattoo work done without having to pay for the work. They tattoo work they set up for me to do at these parties are smaller, less complicated pieces. Examples of tattoos done:
Minimum charge is $45. For a small black design (like a name or small tribal)
Minimum for a small color piece is $60. (heart, rose, sun daisy, ladybug,etc.)
