In the diorama card below, we have used Nellies' scalloped oval dies and plain ovals dies to cut the two openings. Both layers started out at 8.5 inches long by 4 in. wide. For the top and bottom panels, score each panel in from the narrow end at one inch on each end. The secondary layer needs to be cut to one half inch for the side panels. The top panel will be too long to fit into an embossing folder so we tucked both of the scored panels underneath and ran it through a folder. This leaves you with a positive image on the top of the card and a negative image on the side panels. The stamps are from Stampscapes and we used marker for colouring. If you cut the cattails out of white cardstock, and colour with markers, it is easier to achieve the two colours than die-cutting from two cardstock colours.
