From my 34+ years getting inked (started before I was l old enough to get one legally) tatts have always been on a revolving pattern. All black is in vouge, Japanese is out of favour, couple years on all black is out everyone is getting Japanese, same with Americana or flash and so on.... same flash sheets in every parlour....
The amount of times I've been in the chair when some young lad walks in and asks for a sleeve.. what do you want asks the artist, I dunno just a sleeve....
The guy who did a majority of my work (not the best /detailed work but a genuine old school biker (( patched)) bloke ) used to have a rule , if someone came in and asked for a tattoo on what he called public skin : face/hands/neck he'd tell em to f**k off and come back when they'd earned it as in getting enough ink in less visible parts.
It was his way of stopping youngsters making bad life decisions, nowadays people seem to start on their hands and necks to appear more inked than they actually are!
Bloody kids (old man shakes fist at sky.....)
