The other day I had an interesting question via email:
“In your writing tips, you warned against submitting photos or pictures with the text — commissioning your sister-in-law to paint some pictures for the book, for example, is a bad idea.
However, what if the pictures are your own drawings, and you want to be an illustrator as much as you want to be a writer?”
Here is my answer:
There is one exception to never sending in illustrations, and that’s if you’re a professional artist. Even so, the best way to handle it is to submit the story without illustrations, but to mention in your cover letter that you are an artist. If you have a sample that can be viewed online, give them the url.
Another way around it is to submit your art portfolio without your story.
If you’re an illustrator, consider making up postcards and sending them out to editors.
The reason you don’t want to submit both at the same time is because it gives them two reasons to reject you. What if they hate the story but love the illos or visa versa? That said, there are some publishers who specifically request submissions from people who are both author and illustrators. Those ones should be on the top of your “to submit” list.
Good luck with your submissions!
