A very elegant way to dress up your stamps is called Stamp ETching. You can see the tutorial on it HERE. I have been wanting to play a bit more in the Splitcoast Stampers challenges and this one was chosen by a Team of four of us working together. Using neutrals we chose to use this technique for a CAS (Clean and Simple) format.
I love the way it turned out but I doubt it will be a technique I would use often. You must have an open line stamp to do this technique.
