An email from Sera Waters in Australia really caught my attention. She has an entire series of cuts of meat meticulously stitched in blackwork style stitches. Blackwork (traditionally worked all in black thread on an even-weave fabric) is an extremely complex pattern, somewhat like honeycomb, used to create the illusion of shading and various gradations. That's an over-simplification of it, so check this out for a better idea of what I'm trying to say.
