Prickley Pear! I am a big fan of dandelions, so I love this heart stamp that resembles one. I paired with a background made with distress ink and water and some black accents. Don't you pink and black together?
Stamps: GG0132 Heart Dandelion, CLR013C Scalloped Circle & Oval 4 - Floral
Be sure to check out the blog for more inspiration. Here's another more traditional valentine that I used it on as well. I'm never sure about pink and red together, but this designer paper is fun.
