Josh, what type of portraits are you thinking of selling? Is it portraits of actors and famous people, or, is it of a personal portrait of someone's family member. If it is a portrait of an actor or a famous person, then it's a matter of waiting until the right person walks by. If it's of someone else's family, then those are usually special orders. And to get those special orders, you have to get your name and work known by others. To start try cutting one for a friend or family member who is celebrating a birthday or anniversary, of course this one is done for free. Hopefully, they'll show it to a lot of people who might be interested in buying one from you, that is how I started selling the ones I made. Now, I have people calling me, asking to have a cutting done for them. Don't think that just because you like something that other will, ask around and find out what is popular in your area, or, what other people might want t see cut out. But really, it's all a matter of getting your name and work out there.
