Melanie Cantrell made the pretty Valentine felt heart pin shown below. Melanie tells us that she used her Big Shot Die Cutting Machine that she she got from Santa to cut out the felt hearts.You can see more of her Valentine projects here on her blog.
Another interesting idea comes from Trina McClune. Trina made the Valentine project below after being inspired from something she saw in a shop at the Auckland Airport. Here is how she made it: "I used a black chipboard heart, which I painted black. Once dry I layered buttons and beads using glossy accents to adhere. It only took half an hour from start to finish! A nice quick project."
