SCBWI-IL Postcards from the Prairie


Welcome to SCBWI-Illinois' Postcards from the Prairie Marketing Initiative


Creating a Postcard Mailer

Even in the Internet age, physical postcards are still one of the most effective ways to get your art seen. 

For the Postcard Initiative, we’ll focus on marketing and mailing postcards to buyers in the children’s book and media industry. With that intention, there will be 4 target dates for finished art (March 1, June 1, Sept 1, & Dec 1) and then it is up to each illustrator to upload them to the printer of their choice and mail them!

Finished art will be posted 4 times a year on a closed Facebook group page for all members and contributors to view.



There are a variety of online companies and printers to use. Printers will supply templates to help you layout your post card.  Check out USPS online guide for postal requirements mailing template.



The most important element of successful postcard design is well-executed art!

Beyond that, think about the best use of the card’s space, vertical or horizontal, and how you’ll incorporate your contact info.  

Think about how to make your card stand out from the rest.

Send your finished postcard illustration to  beginning 3 days before the target date for inclusion on our facebook page SCBWI-IL Postcards from the Prairie.  Members and participants will be invited to view them all!

Choose your size

 Make sure your art fits, ratio-wise, to your preferred size.

Upload according to printer specs

Varies with each printer, but usually 300 dpi, CMYK mode.  Printer will list preferences.

Mailing Lists & Website

Research the market for the best fit for your art and have a list or ready-to-go labels.  Make sure your website reflects your best and freshest art, including the image you’re sending!
