With my new job and since Im the new kid on the block I have to cover up my tattoos on my arms...Ive got the whole liquid foundation thing but was wondering if anyone had any tips or tricks that I could try out. 

Where are they? Mine are pretty easy to cover, but I only have 4, and as long as I am wearing a regular t-shirt only one is visible. If I need to cover the one that's visible I wear a watch.
Ok, after all that I guess what I am trying to say is if possible, maybe put jewelery in strategic places? Also if you have any on your neck you could wear collared shirts and maybe scarves when it gets cooler out :) 

I have roseacea & use a product made by Physicians Formula, it is a mineral wear correcting primer in a green tube, a family member also uses it for scars, it may help you to need less cover up? 

well i have a bracelet around one wrist so an easy fix for that is using a watch but then i have a weird shaped one on the inside of my wrist...i tried cover up make up today and it worked (just gotta match skin tones) but im afraid of it wiping off or something. i have one on my chest (in between my boobs) but thats easy to fix. i have 8 total in which 5 are normally visible. 

So everyone doesn't have to cover theirs up? 

How about a band-aid?

Worst case scenario, you could always wear an athletic wrist band
