To make money with comic strips, you might consider collaborating with brands for sponsored content. Or, self-publish and sell your comic strips as digital or physical books. Additionally, offering commissions based on your comic strip style could be a source of income.
You can sell your comic strips to publishers or online platforms. Also, you could offer them for licensing for merchandising.
One way to make money is through crowdfunding. Present your comic strip idea and get supporters to fund your project. Another option is to create a Patreon page where fans can support you monthly. You can also sell prints or original artworks of your comic strips at conventions or online.
