the current sketch at Freshly Made Sketches to put together this clean and simple--and pretty flat--design using stamps and dies from SugarPea Designs. I combined text stamps from two sets, Special Delivery and Espresso Yourself, to create my own sentiment, stamped in red ink on a white panel. The gray envelope was created with the Special Delivery Accents dies. I used foam tape to adhere it to the card. Even with the bit of added dimension, it's not too thick to make it through the mail easily. I matted the panel on red cardstock, then added two red heart washi tape tabs to the left edge before adhering it to a gray cardstock panel. The finished panel was adhered to a contrasting red card base.
