By Katie Mai Print Club

Katie Mai, a children's book illustrator in Southern California, runs her happy mail through Patreon. Depending on the tier, each month's envelope brings an exclusive 5x7 print with a postcard back, a vinyl sticker, or both, always with a letter and a small thank-you surprise. The top tier adds a bookmark.

Tiers are $10 a month for the print or the sticker alone, $15 for print plus sticker, and $18 for print, sticker and bookmark (US only). Mail goes out with stamps at the start of the following month, so join before the last day of a month. International patrons are welcome on most tiers, and international shipping reopened in September 2026.

Every paid tier also unlocks her monthly wallpapers and printables.
