I loved the idea of the stripes on the sketch. To do this, I created a mask at the top and bottom of my card, leaving the amount of space between the two that I wanted for the stripes. The color really is gray I promise. I really like how it turned out.
Here is the sketch and colors:
Stamps: Papertrey Ink Stylish Sentiments Birthday, Beautiful Butterlies & Backgroud Basics: Super Stripes
Inks: Papertrey Ink Smokey Shadow Stampin' Up! Melon Mambo & Daffodil Delight
