There's a reason this technique is called Hidden Image. Unless you look very closely, you might miss the knight stamped all over the background. Actually he's even more obscure because of scanning. He can be seem much better on the actual card. The Try That Technique challenge this week is the Hidden Image technique a bonus technique on the 2010 CD. This was a fun technique to try and I got to use my My Knight stamp sheet from Artistic Outpost.
