I stamped them using basic black, green galore, or real red ink from Stampin' Up!
I punched out the stamped image with Fiskars scallop circle punch and cut the red scallop circle using Cricut Expression Mini Monograms cart.
I love using the autofill option and cut as many images on one sheet of paper. Works great for class projects such as these. I cut strips of paper for him to add the To and From. I think they turned out very cute. Happy Valentine's Day!
