Use photocopies and illustrations as necessary to illustrate your text. Some well-chosen pictures can really enhance your documentation. For example, a photocopy of the original recipe for mead, goes a long way. IF you wish documentation for whatever reason, merely condense and edit your project diary. At this point, the documentation is easy to create.
Brevity is important.
Typically one page of text, possibly two for very involved or detailed projects. Footnotes can be broken down three ways. Avoid the things that everybody knows. Document the stuff that someone else said or the stuff you made up. Format your documentation according to the constraint categories with extra categories for special things, like artistic design.
