something longer than wide but fairly small, i have small arms. If it's half way between the back of my elbow and back of my shoulder would it be visible often with a tshirt on? also...suggestions for anything to get? i like tattoos in black and was thinking of somethinng like two saints but ca't find a right design. One maybe St. Micheal? i know it's from a movie but i like simple designs like this: i'm a biology major....if i was going into genetics i would get a half of a double helix on each arm back. thank you.
