well probably best to start from the covered areas on out - go chest or upper arm or thigh - plenty of areas to start with that will be typically covered in a workplace environment
i would love to go on my lower arm areas but i have concerns as well working in a school environment (I hate / never wear long sleeve shirts)
havent ruled it out the placement though for future ink
but in the meantime - i got plenty of space to play with
i'll worry about it more once i've heabily covered the other areas
anyway - good luck
