The challenge is to add letters, images, patterns or anything you can think of that creates a tone-on-tone appearance.
You have lots of freedom with this challenge - whether you use paper or embellishments there must be an overlap between at least 2 elements that creates a tone-on-tone look.
Made this card with Outlawz Creative Freebie Challenge May 6-19 in mind, using the 2nd digi image for the challenge, the shoe or boot or boot shoe, on different tones of cream and brown. The shoe (colored in pencils and embellished with pearls) is mounted on the card with floral sticker, embellished with some gems. A biege tag with sentiment serves like a base with two ribbons, brown on biege (or cream).
