With this method you colour the background with several colours of dye ink. After it is dry you use a background stamp dipped in water and stamp on the inked paper. I love the result of this. I also water stamped the sentiment 'card' making it so look like the stamp continues on both pieces of paper. The tutorial on how to do this can be found on Splitcoaststampers.
On to my next card trying a technique I have never done before and . . . . using another one of my stamps.
