To submit comic strips to publishers, start by compiling a portfolio of your best work. Then, check the publisher's website or contact them to find out their submission requirements. It's important to follow those exactly. Sometimes, you might need to include a cover letter introducing yourself and explaining the concept of your comic. Good luck!
First, you need to research and identify publishers that are interested in the type of comic strips you create. Then, follow their submission guidelines carefully. This might include sending a pitch, samples of your work, and a synopsis.
