Well, I came up with a way to do it (although a much easier way occurred to me as I was struggling to cut a prefolded card to shape with a craft knife... too late! well, I'll know how if this ever comes up again!)
Here is my shaped card, basically a paper-pieced owl:
- Die set: Sizzix "Owl #2" (657694)
- Papers: Authentique 6x6 "Spirited" (SPI018), The Elegant Stamp "Cranberry" Layering Card Kit
- Stamp: Hero Arts "Just Because..." (A freebie)
- Inks: Archival "Jet Black"\
- Ephemera: Making Memories "White Tagged Circles" (20949)
