Multi-session pieces
- For sleeves and back pieces, tip at the end of each session based on that session's cost. It rewards the work as it happens and keeps each tip manageable.
- Some clients prefer one larger tip at the final session. Either is accepted, but per-session is more common.
Touch-ups, flash and custom work
- Free touch-ups: a $10–$20 tip is a nice gesture for the artist's time.
- Custom designs with extra drawing time deserve the upper end of the range, since design hours are often unpaid.
