I created this layout with the Sock Hop kit from Studio Calico. Love the bright colors. If you look closely, you can see that I've cut the star shapes out of the background paper with my Silhouette. I then put the patterned paper on the back of the layout, to show through the shape to the front.
If you have a Silhouette, this is a very easy technique to try out. If you don't, you can handcut a shape from the paper or use your punches to shape the background paper.
Give it a try - I think you'll love the results.
