These xray markers make me think of laying below the stars..star gazing* :) Just like the sky at night, the stars will vary slightly in position- no two are identical.
*Please leave in notes section the initials you would like. These can be made with 2 or 3 initials: If 2 is needed, they will be placed underneath the L/R in a horizontal direction. If 3 is needed, they will be placed next to the L/R in a vertical direction.
