Masking is such a simple and wonderful technique! Masking involves sponging color in or around a particular shape. For this card, I took a scrap piece of paper and punched out three 1 1/4 inch squares. I decided to offset the middle square a bit to give it some variation. Next I took the template, laid it on the left side of my whisper white cardstock and sponged the inside of each square with a different color. Once the sponging was completed, I stamped one of the serene silhouette images over the top of the sponged squares. Try it out and let me know what you think! 🙂
