About the pattern book, I wonder if upscaling is the way to go? I'm worried that this might take your work out of the arts arena into the crafts arena??? What about a downscaling book? Anyway, just a thought. Or maybe a pattern book that does both upscaling and downscaling? You can probably get a better feel for exactly what they want when you get their materials. Just read them carefully, and then craft your proposal to match their needs.
