Yes I had to think about that one, so I hit that well known authority, Google.What the heck is stamped image and a clear element - oh boy..
From what I can gather:
Stamped images are just like we make with rubber or acrylic stamps. Only now they've become digitalised. I kept mine black and white, but of course you could recolour them.
Clear elements, I think, are like the acrylic pages that some people are scrapping onto, but now they come in shapes for embellishments too.
If I'm wrong, then perhaps someone else can enlighten both of us.
