Here's another "clean and simple" card for you! This would be a good "warm up" card! I used the Stacked with Love Designer Paper Stack from the Occasions Catalog and the Heart Punch. With all of the different patterns in the Stacked with Love pack, you could make a whole stack of valentines!
Stampin' Up! Supplies: Teeny Tiny Wishes, Crumb Cake cardstock, Basic Black ink, Blushing Bride cardstock, Real Red Textured cardstock, Stacked with Love Designer Paper, 2" Circle Punch, Heart Punch, Rhinestone Jewel Accents
