It’s a A2 card size just folded and cut within the Nestability shown in the 2nd picture. I often do this and keep the folded edge of the card inside the template so it doesn’t cut my card in two. I used a white card and "xyronned" the image to the front and distress the edge of the nestability with Wild Honey Distress Ink. Very subtle. I also used a starlight clear sparkly gel pen on the flower pets edges and the edges of the dish.

I am also a square peg in a round hole - or at least it feels that way most times!
