The challenge at Mark's Finest Papers is Silhouettes. I've been wanting to use this for a long time but just hadn't take the time to get it together Today was the day! It didn't come out as well as I had hoped but I decided just a splash of Yellow was enough to make it pop! I will also use it in the CAS on Sunday Black white and one other color Challenge. Treasured Times Rubber Stamps has an Anything Goes Challenge.
