21 Easy-to-Mail Printable Valentines

This mailable kit doubles as a Valentine's Day card and a fun little craft for recipients - they get to construct and accessorize the cat and display their creation in front of a cozy cafe backdrop. The craft kit prints on three pages of printer paper (use card stock for best results) and includes the backdrop which doubles as a card, two 5x7 sheets with all the pieces to construct the cat, and one 5x7 instruction sheet with a reference image. The kit is designed to fit into a standard A7 envelope for easy mailing!

I've also got an adorable fox version of this craft kit! As soon as your payment clears for these kits, you can instantly download the files and print as many as you want to send to all your loved ones. Even an inexpensive home printer can handle printing these kits on card stock.

These folding cards show an unhatched egg when the recipient first pulls it out of the envelope and then reveal a hatched baby dinosaur when they unfold it! They measure 5x3.5 when folded and 5x7 when opened and they have dotted lines to show you where to fold. This variety pack includes a t. rex, pterodactyl, and longneck dinosaur, and each design is also available for individual sale.

I also made colorable editions of the dino egg folding surprise designs! This variety pack includes a longneck, triceratops, pterodactyl, and t. rex and again each of those is available for individual sale as well. These are great for young kids to color and send to grandparents or other family members, or you can send a few crayons or colored pencils along with the card as a fun activity.
