Step 2). I used one of the Lawn Fawn cloud dies and 2 of the SSS slope dies to die cut a sheet of the masking paper into thirds. Pay attention to the spacing because you'll be ink blending over the cut edge and you'll want a bit of space to avoid any unwanted smudges. If it's not wide enough, just use a piece of scrap paper where you need it.
Step 3). I started at the bottom of my cardstock, working my way up and changing the shape of each layer of ink. Looking at the picture, the blue side is the positive side of the die and the purple is the negative side of the die. Each time I moved the mask to add a layer of ink, I changed the color and used the negative side to mask the layer I just finished inking. The picture on the right gives a better example of the process.
