  • I want to do art commissions but have no idea how to do them?

    I'm a traditional artist and i really need money to get Christmas presents for my family and friends this year, i'm super broke at the moment, and i heard about commissions but i'm not sure how to do them right. I know that if someone contacts you for one you draw what they want you to and then they pay you for it once it's finished. I guess what i'm really confused about is if you need to send a physical copy to the person or if just sending them a picture of the drawing when it's done is all i need to do. I'm still pretty confused about it all and i want to start asap so any information about how to do art commissions is extremely helpful.
