Artist bios are an important part of art.
No matter the form of art you do, if you're selling—or seeking to sell—your art or services, you'll want to create a bio that evolves as you do. Your bio is your story in your words.
If your art is your hobby or passion, and you're not sure if you want it to become something more, this may still be helpful for you. Your art and those who admire it, will all benefit by the addition of story to your creations.
