Working with the shape of the chest
Think in terms of three zones. The upper chest, from collarbone down, is the flattest and most forgiving — good for banners, lettering, wings and anything that wants a straight horizontal line. The pec itself is a curved plane that rewards designs with a natural round or oval mass: a lion's head, a compass rose, a rose cluster. The sternum and lower ribs are the trickiest, narrow and bony, and pieces there stretch differently on a broad frame than a lean one. If you want the full chest covered, design it as one composition with a deliberate centre, not two separate tattoos that happen to be next to each other.
