21. Tattoo Challenge 1 - Design your own ink tattoo on paper that has either line symmetry or rotational symmetry. You might consider a tribal tattoo design, a butterfly or any other form of tattoo art. But just remember that a tattoo is for life so you had better like it because I hear tattoo removal is expensive. :) Tattoo Challenge 1 - Design your own ink tattoo on paper that has either line symmetry or rotational symmetry.
