I created the background by scraping off pieces of the AquaBlend pencils (colors Lagoon, Aqua, Violet, Persimmon, and Parakeet) with my palette knife and then spritzing them with water. I used Spectrum Noir Watercolour Cardstock. Cool, huh? I saw the video tutorial on the Spectrum Noir blog and knew I just had to try it! I also flicked some of the Spectrum Noir Crystal Clear Sparkle Marker on the panel, too. To create the card base, I scored some Spectrum Noir Ultra Smooth White cardstock.
