Bit of help in designing my first tattoo.

I'm hiking a long trail, ~880km and won't be done until 2020. When done, I'm planning on gettng my first tattoo at middle-age.I want to get a "left turn" trail blaze (two staggered markers, like this) but with the texture of a tree (as if it were painted on a larger trunk and not a piece of wood. Example picSo.... white (no ink) rectangles (with some shading for bark texture) and black outlines. Simpler is better but I do want some texture to indicate tree bark.Can anyone sketch this out, or is the wrong sub for that?Thanks. https://ift.tt/2DArXLN
