For my inspiration I may have went a little overboard with all of the layers but I really like it so I guess for me it isn't overboard.
I used four different designer papers for this and three colors of solid cardstock. I cut them in a variety of shapes. Have you ever tried just cutting different size squares and rectangles? Even though dies are great using different size shapes works wonderful and it is very quick! I use measurements such as 1/4", 1/8" and 3/8" depending on how much of the other paper I want to show.
I hope that I have inspired you to layer it up!
