Have a Jawsome Valentine’s Day!
DIY shark Valentine cards are a fun and creative way to celebrate Valentine’s Day, especially for kids who love ocean animals.
My son likes sharks, so we went with a Great White theme for Valentine’s Day and made shark cards with two real shark teeth attached. You can find real shark teeth in bulk on both Etsy and Amazon. (click here to see them on Amazon)
The best paper I’ve found for printing cards is either card stock or thicker photo paper. The printable option doesn’t have the name at the bottom, but you can edit it before printing to add the name or write the name on after printing.
Shark teeth are optional! I attached the teeth with a little dot of hot glue.

The image below shows what the print will look like, but I recommend using the download rather than copying the photo below. because the download is sized correctly to print on an 8.5 x 11 paper.

A Little History About Valentine Cards
The tradition of exchanging Valentine’s cards in schools has been a beloved activity for generations, bringing a sense of fun and friendship to classrooms. The practice has evolved over time, but it remains a staple of childhood Valentine’s Day celebrations.
Origins of School Valentine’s Cards
The tradition of sending Valentine’s cards dates back centuries, with the first known written Valentine appearing in the 1400s. By the mid-1800s, the mass production of Valentine’s cards made them more accessible to the general public. By the early 20th century, Valentine’s exchanges became a popular school activity, especially as printed cards became more colorful and affordable.
The Rise of Classroom Exchanges
During the 1940s and 1950s, Valentine’s Day card exchanges became a classroom tradition in the U.S. Teachers encouraged students to make or bring in cards to share with their classmates. By the 1960s and 1970s, boxed Valentine’s cards featuring popular cartoon characters became widely available, making it even easier for kids to participate.
Crafting & Creativity in Schools
Many schools also encourage students to create their own handmade Valentines as an arts-and-crafts activity. This DIY approach allows for creativity and personal touch, making it more meaningful. Decorated shoeboxes or paper bags have long been used as “mailboxes” for collecting Valentines, adding to the excitement of the holiday.
You can get your child involved in making these cards, by letting them cut the cards apart, adding each child’s name to the card, and glueing on the teeth.
Modern-Day Traditions
Today, the tradition continues, with many teachers setting guidelines to ensure that every child receives a Valentine to promote inclusivity and kindness. So, make sure to get the total number of children so you can have enough cards for everyone.
Have a Happy Valentine’s Day
DIY shark Valentine cards offer a fun and creative way to celebrate Valentine’s Day, especially for children who love marine life. By incorporating this engaging activity into your Valentine’s Day plans, you can create lasting memories with your child while also inspiring their creativity. Whether you opt for shark teeth or stick with just the cards, these unique valentines are sure to be a hit in classrooms and amongst friends.
Encourage your child to take part in the card-making process, allowing them to personalize each one. With cute messages and a little bit of crafting, you’ll ensure a Jawsome Valentine’s Day for everyone involved. Happy crafting and have a wonderful Valentine’s Day!
