Searched the subreddit for tattoo recs and didn't see anything dealing with this specific question, so:

In an ideal world I'd love someone like Carrie Metz Caporusso who does beautiful pieces that incorporate fat rolls in the design, but I'm also fine with someone who does regular tattoos but shows tattoos on fat bodies in their portfolio, and especially belly tattoos. I've gotten some great tattoos on firmer parts of my body and no one's been mean to me, but I feel like maybe tattooing the really fat parts (and designing for those parts) should be done by someone with experience in it. I'm willing to travel to: Lafayette, Shreveport, DFW, Austin, San Antonio, Corpus Christi, and anywhere in that circle, though of course closer is a big plus.
