This kit is compatible with the Home for the Holidays Truck Book Stencil in size XS. I used a standard book and spray painted it black. Head over to my YouTube channel to see the whole process in action. The kit I made came out to about 9½" by 6⅓", but you've got options—there are different stencil sizes available, so pick whatever works best for your book cover. And hey, if you'd rather skip the book altogether, just grab a piece of wood instead. Super flexible, totally fun. Kit is four pieces and cut from 1/8" birch wood
