These are tattoos that took more than one or two sessions to complete.  This might give you more of an idea of how long it takes to complete larger projects. 
Photos here will be added until said project is complete and the final will be moved to its appropriate gallery.
Carla... is an ongoing work in progress.
We started with her right leg.  Then proceeded to work on her left arm.  Eventually we'll be joining the two limbs
across her back.   I felt it was absolutely necessary that she gets her own space in the progress gallery.
