I have called this "scraplift" in my file, because the idea came from a layout I saw recently where there was several pieces of torn paper stacked under the image instead of a mat - but I don't remember where. It may have been on Pinterest. The image has stuck in my head as something I want to try, so I've sketched it out, and added some different ideas for the background.
I want to have some tags and ephemera - some stamped images. And most importantly, some stamped vellum. I will be working up some single image, remnant using, stamped embellie layouts for this.
