Cheers for you inputs.
seems that just softening the edges would work best.
I always thought Tshirts were a great way to advertise your work as long as you keep your signature on them (ideally you would want your web address on there too) it's a good way to get recognised to the man on the street as it were, something eye catching where you wouldn't so much expect to see it, and some people just don't want Art for their walls...they wanna see it everywhere :)
I'm keeping what I do for Tshirts in a seperate file.
I still think it is good to have a choice of what you can buy, Pixels and FAA are in effect the same company, and you can share which ever item you happen to be selling (be it merchandise items or prints) on other social networks.
It's just about getting out there what ever way you can!
