I've been enjoying this process so much (see previous pages here) and only have three left to complete (just click on the images to enlarge). In these pages I've included copper leaf, modeling paste, and mixed media, along with all the other materials mentioned previously.
The interesting thing about working like this is that I begin several pages throughout the book at once (I slip a sheet of waxed paper in between to keep pages from sticking together) and then continue working back and forth. When techniques or images or media present themselves, I can begin another page or work on one that's begun...and I like the fact that several pages come together at the same time, and that even though I have no idea what the whole project will look like at completion, they all seem to work together.
I think this would be a fun all day workshop. Not that it could be completed in one day, but it would be a great beginning. It's always interesting to see a group of people come together to work as the ideas really fly. It's a collaboration of sorts.
