Three chipboard roof border strips and 3 window toppers. Note: you can overlap the roof strips to make a wider border (all 3 together would make a border approx. 11" wide; and you can flip some of the strips over to vary the shapes).
Shown in one of the photos with the facade from the Large Haunted House Shadowbox (the window toppers will fit all the windows in the top floor of that shadowbox; I'd crop out the middle of one topper so that the skinny window in the middle would have "snow" at both ends).
Hint: slather on some Dimensional Snow and Diamond Dust for sparkly icicles.
Note: this will ship in a flat sheet: almost completely cut out, save a tiny (1/8") spot that you can snip with scissors or a sharp blade. Keeps all the pointy details from being banged up during transit.
3 strips & 3 windows (approx. 3-3/4" and 2-1/4" wide, respectively.)
Design Team Member Laura Carson made a Santa's Workshop Diorama (see the wide photo below). More info in the blog and/or see the supply list.
