What's interesting is when I was in undergrad I actually had a button business. I designed and created my own buttons, promoted them and sold them, but had someone else actually make them.
So now it's flip flopped and I didn't design, nor will I sell. I'm just making them. It's good experience though to see the other side and I'm glad I got to do it although unless I open another very small button business I don't think I'll have much reason to do so again.
My skills are masterful however, so if you'd like to hire me to make buttons, I'm available at an all call basis. Proof of my work:
