I recently purchased Lawn Fawn's Stackable Hearts and AGAIN CASE'd Laura Bassen. These hearts are a bit smaller so they actually fit within an A2 sized card. I used distress inks for the shading: Spun Sugar, Picked Raspberry and Worn Lipstick; I sprinkled on some MFT Shimmer Mist and Mister Huey's Opaque White. Just like Laura, every other heart was raised with dimensions. I cut the arrow and "U" from American Crafts black glitter card stock and placed the arrow behind the tiny heart right in the middle.
I spy some new washi tape too (inside of card and envelope - pix on the blogarooni)! I added 3 embossed lines at the bottom of the card to finish it off - pretty clean and simple with lots of white space but oh how I love the sparkle and shine!
