This idea was shared at our monthly demo get together this week and for me it was one of those ideas that I wanted to hurry home and use! I love it!  
I purchased the sticker paper at Office Max- make sure it is the removable sticker sheets- so that you can take the pieces off easily. I cut a sheet of sticker paper to fit over the whole die and using the corner rounder I rounded the corners. I then attached the paper to the die.

Then run it through the Big Shot. Take the sticker sheets off of the images.

Now you can see the images- now for the best part! Mark each image with the size you cardstock or material need to be to cut the image!

Hope you found this as useful as I did!
