I made this quickly for my boyfriend, since we go sailing, biking, hiking, and beaching together. The line "You & Me, Land and Sea." seemed appropriate. I did all the type by hand and scanned it into Photoshop and colored it. Not my best work, but still fun!
Sorry it was rushed, but if you like it you can download and print it here and fold it up for your land & sea loving valentine.
(ps: sorry for the crappy iphone picture) Below is a little video on how to fold the card... but I'm sure you are smart enough to fold up a card!
