I love my friends. I do. But a few of them that are not artists need to realize that those of us that are should get paid for their work and not just used under the word “collaboration.”
"Collaboration" is what happens when two or more people bring something to the table and combine it. Not one person asking for something to get done for them for free.
(side note: I do make art for friends for free on occasion. But not under the guise of “collaboration.” I just call it a gift.)
