Valentine’s Day might be even more fun before it comes with the pressure of flowers, dates, and gifts. You know, back when everyone had to get a card for the whole class? But kids need a place to house that haul of Valentines and candy from friends and classmates. This year, instead of just using a plain old box, why not turn it into a bit of an activity, and an excuse for the whole family to take on a fun project together—nothing says love like some solid bonding time, after all. Here you’ll find a half-dozen ideas for transforming a standard container (think: a shoe box, a cereal box, a tissue box, an oatmeal container, or even a mini trash can) into a super cool mailbox that’s ready to welcome an abundance of Valentine’s Day cards and treats. It’s easy to get started—to create the simpler boxes (the heart-eye emoji box, the woodland creature bags, the train, and even the cupcake garbage can) you’ll just need a few basic craft supplies, like scissors, tape, and colored paper. Even the more complex (the unicorn and the robot) only require a few extras, like ribbon, stickers, or wrapping paper.
