I'm sure there are a variety of ways to create "rays", the technique I use involves my trusty magnetic mat, ruler and a craft knife. After cutting each ray, I placed it on the background cardstock, rearranging pieces until I was satisfied with the layout.
After all of the sunburst rays found their final resting places, I added the remaining layers covering the overlapping corners. To create more precise rays, mark a center point in pencil on the back of your paper, then draw lines with each running through the center point.
