To create my background, I did a variation on the Smackin' Acetate technique I learned years ago. For this version...I used a piece of acetate (because my craft mat has slices in it, a craft mat would work as well). I grabbed three reinkers in soft tones, some water in a mister and then some water/pearlex in another mister. One more thing not pictured is either alcohol or alcohol blending solution.
Drop some of the reinker around on the acetate and then spritz with water or the pearlized water as desired. Then, working quickly, add a bit of alcohol and using a piece of white cardstock, mop up your mess!
Once dry, emboss the panel if desired and it is a fresh and fun textural delight!
