I made these for my daughters to hand out for Valentines day. I thought they turned out pretty cute! I used 2 colors of card stock for each card. I die cut the hearts out of each color used the outline of the heart from the coordinating color, taped the hearts into the hole in the opposite side. Attached the outline color paper to the back with photo mounts. Printed the Valentine and attached it with glue dots. I made these in 4 different colors, using just 2 colors. I just traded the places on half.
