You will need:
A card (or a red piece of cardstock, cut to size and folded in half)
Alphabet stickers (I used chipboard alphas to give it some depth)
Small heart punch
What you'll do:
Step one: Place your alphabet stickers on the card to spell out the word "love".
Step two: open card and lay it flat on an area that is safe to cut into. Then, using your x-acto knife, carefully cut out the opening of the "O". This will allow you to see a little part of the inside of the card... like a window.
Step three: Close card and place small heart in the center of the "O". The heart will be inside the card but will show from the outside.
Step four: Write out a nice, heartful message expressing all your love to your Valentine.
