What do Scooby-Doo, Teenage Mutant Ninja Turtles and Hello Kitty have in common?

Yes, they’re all cartoons. But for many of us, they were some of our favorite Valentine’s Day card themes in elementary school.

Valentine’s Day is notorious for taking over the month of February. Originally, the holiday existed to celebrate a saint of the same name. Today, it is a celebration of love.

The holiday is celebrated differently by people of all ages. As kids, we passed out cards and candy. As college students, we spend time with our significant others or party. However, that distance does not mean we can’t still celebrate like we did as kids.

Channel your inner child this season and party like it’s 1999.

Pass out some Valentine’s Day cards. Themed cards are a clichéd no-brainer and come in a variety of styles and characters.

From Transformers to Powerpuff Girls, these cards are festive, easy to sign and can have candy taped to them. Choosing your favorite TV characters from your childhood will make the card more personalized.

Handmade cards are another way to throwback and personalize your Valentine’s Day. Back in preschool, kindergarten and elementary school, our artistic skills consisted of stick figures and cartoon hearts. They may have not been artistically stunning, but they translated the message in a heartfelt way. These handmade cards add personality and originality.

Cutout hearts are still popular to include, and they can be hand-drawn in different colors and designs. For the handmade cards, include a small poem to convey your feelings. We all know the classic:

“Roses are red, violets are blue

Sugar is sweet, and so are you.”

This poem is traditional and the words can be changed. Try making a new poem for a dash of originality. If the poems don’t work, then just include a small message for the receiver of the card.

If you remember the kindergarten cards, you may remember the mailboxes we made for when our classmates delivered the cards to one another. These same cardboard boxes can be made using colored paper and decorating them by drawing hearts or plastering them with stickers.

To make the mailbox, start with a strip of 8.5 by 4 inch paper. Take an 8.5 by 11 inch piece of paper and curve it to make the mailbox shape. Tape or glue this to the first strip. Cut out a piece of paper to cover the back of the box.

For a door, cut out a piece of paper the same shape as the hole. Leave extra room to fold over and tape to the bottom of the box. Add some string to open and close the mailbox. Cut out a flag shape and tape it to the side of the box. Then you’re free to decorate the mailbox.

Reverting back to a more innocent version of Valentine’s Day will make you feel like an 8-year-old once more.
