How hilarious are these cards by illustrator Emily McDowell? So after greeting can seem staid or trite—after all people have been having babies and birthdays since the beginning of time and it's hard to find new ways to say 'Yay!'. But McDowell has some pretty clever takes on celebrating those important moments in our lives, plus some lovely illustrations to boot. Bonus: she also reproduces her work onto bags, mugs, prints and more. I recommend you check them all out here.
