When I saw this card on Lyssa's blog, I knew it would be the perfect Valentine card! We made it at my last workshop, and everyone loved it! The finished card is 4 1/4" square. We made a matching 4 1/2" square envelope using the envelope punch board. Here's the link to Lyssa's tutorial. I found that the front lined up perfectly when I scored just shy of 2 1/8". I also added the Soho Subway DSP pieces on the front. It's a 4" square piece of DSP cut in half. The heart is punched from the same DSP. You can make the card and envelope from one sheet of DSP and still have a little left over! The sentiment is from A Round Array and is punched out with the 7/8" scallop circle punch.
