Trim the cards to size using scissors or a paper trimmer.
Fold the card in half.
Use a 1.5" Round Craft Punch to create a circle through the middle of the folded card.
Unfold card and have your child (or yourself) fill out the "To" and "From" portion of the cards.
Fill a mini ziploc bag a little more than 1/2 full with sprinkles of your choice.
Refold card and slide the mini ziploc bag filled with sprinkles into the middle of the card.
Staple the card closed - being sure the staple penetrates through the top of the mini ziploc bag.
Repeat these steps until you have finished making the desired number of cards.
There you have it a super fun Valentine - "You are the Sprinkles to my Cupcake" Chalkboard Art Valentine's Day Cards!
OPTIONAL: Present a frosted SPRINKLE-FREE cupcake along with the Valentine's Day card shown here. Simply send in (or bring in) some mini cupcakes to present to each child along with their "Sprinkles to my Cupcake" card. Now each child can have double the fun by decorating their cupcake and THEN eating it too.
