Hard? You could say that.

It was hard to get the transparency right so they didn't have little sections of white around them. And I had to get them out of their original pictures, separating them from their backgrounds.
They're not too hard to make for me now, but when I actually made them, yeah they were really hard to make. I could make a new one in less than 30 minutes now though, as opposed to the hours I spent perfecting them before.
