What's a fiber fat-book? I suppose it's sort of like an altered journal with fabric pages. Check out the craft-along on craftster and drool over the loveliness on the thread :)

As someone who had a very hard time creatively 'letting go' projects like this are awesome, they are just giant experiments that have no right or wrong. There's no need to trim every thread, those dangly bits become wonderful parts of the whole. It's more about space, colour, texture and the creative process.
That sounded FAR too artsy so I'll shut up now :)
