Trying to design a tattoo for myself for my lower leg that encapsulates an idea of True Fun and the 3 elements needed to have it. Looking for something relatively simple, but meaningful, as this concept is important to me and the tattoo will serve as a reminder to me of what is needed to create True Fun and the value of seeking it out. More detail on attachment. Questions welcomed. Tattoo must be able to fit space, be realistic (i.e. not so small it cannot be tattooed properly) and in a format that can easily be shared with tattoo artist.
