I hope that way of thinking doesn't stop you! My brother is thinking of a same style of tattoo.
A few years ago I designed my own. I wanted "faith, hope, love", but not in the way everybody already does. So i started drawing. I wanted something clean, minimalistic, and thus I started with a horizontal line. That line was crossed by another line, making the first part (faith). Another line crossing the horizontal one with an added arch made the second part: the anchor representing hope. And finally, one other bowed and dented line would end the horizontal line by making the right half of a heart, representing love.
After quite some time, i made up my mind about where to get it tattooed. I decided it should go on my right side, but then i didn't want it horizontal, but vertical. So i redesigned it with the same elements, keeping the half heart, and this is the end result:
