I didn’t create this by the way, I got it off the DVD and just erased out all the background in order for it to be tidy enough to put on a T shirt. Still, took a good few hours to get the edges crisp. Good practice for me on Photoshop anyway.
I so wished I’d discovered magic eraser function earlier. D’oh! Did the whole erasing process using the mouse and various sized erasers. Sheesh, well it’s a learning curve innit?
