Here is a picture of the Susan's Garden 3-D Book package along with the box I created. It is one of the long Sizzix dies that you need to use the Extended Cutting Pads with to die cut it. To create a very solid box, I recommend purchasing Craft-a-Board from Ellen Hutson, LLC. This board is thin enough to be used with most diecut systems and dies, yet sturdy enough to produce beautiful projects. I covered the Craft-a-Board with Design Paper.
To decorate my 3-D Book (box), I created a poinsettia using Susan's Garden Poinsettia Dies. I also used the Susan's Garden Christmas Holly and Susan's Garden White Pine Pinecones dies for fillers under the poinsettia. A sparkly white ribbon was used to close the book.
