i found the above links to pages on paste paper making. although paste paper can be made using a basic formula of 1 part flour to 5 parts water, which you cook and then use with water colour (for transparency) or acrylic colour (for solid colour) to cover your paper, the more complex solution in the martha stewart recipe may be more durable. also, it will be glossy which is great for covering boxes or book covers.
the second link has very simple, clear directions. something i value when following any kind of recipe, whether food or painting. good for making the pages for a book. since my lesson plan for basic book making will be on the accordion fold format, and i am not sure what kind of students i will get, i think pattern play will be a good way to begin.
