Welcome to the easiest DIY project ever! Step one: order a set of 48 miniprints from Printstagram. Step two: arrange photos into a heart shape. Step three: tape/glue photos to cardboard (or like me, use two sides of a cereal box). Step four: attach twine with tape. Step five: hang on a nail.
$12 and 30 minutes later, ta-da! A perfect instagram display (in real life). Enjoy!
