DIY Valentine's Day Mailbox Collection

DIY Valentines Mailbox Collection

My little girl, Lily, loves bright fun colors and is already working on decorating Valentine’s Day cards, so I got a head start on making a Valentine’s Day card box to collect cards from her friends. She loves unicorns, but I love cacti and narwhals, so I decided to make all three. I figured she might have a friend or two that would want a matching one! Astrobrights bright colors made it so easy to create fun boxes that will stand out and I know Lily is going to love the Unicorn! 

General Supplies:

4. Cut out a 2in x 4in piece of Fireball Fuchsia, trim into a flower petal pattern of your choice and leave a half inch band at the bottom. Gently roll the rectangle and glue to form a paper flower. Then attach to the back of the cactus with glue.

6. Cut a 5.5in x 5.5in square from a piece of Terrestrial Teal paper. Next, write a message on the bottom half with the white paint pen and set aside. I suggest the message, “Hey You’re Lookin' Sharp!’’
