Via Lateral Action, I discovered this post, How to Start Licensing Your Art (and Why You Should) written by Natasha Wescoat.
I like what Natasha says about Making the Pitch:
"You can create your own opportunities. Make yourself known to companies you want to work with. Research their sites, their brand and then write a thoughtful letter describing your interest and make a brief introduction of yourself."
"Offer links to your work, as sometimes attachments are marked spam or they won’t open. Show them how THEY can benefit. Not just that you want to work with them. Show how you two fit. Link to the best examples of your work that complement what they already license."
Check out the rest of this informative post. And start taking that first step to Licensing Your Art.
