Have you heard of the Sketchbook Project? I participated in it this year - they describe it as "...like a concert tour, but with sketchbooks." Basically you choose a theme for your sketchbook, they send it to you in the mail, and you do your thing to your book then send it back to them, then the sketchbook goes on tour to different venues for people to check them out (like in a library). My theme was "this is not a sketchbook", so I decided to use fiber. I took the book apart and removed the paper - I printed text from a book onto fabric - then I used the sewing machine to stitch over all the unwanted words to create a new story or "found poem" - then I stitched the fabric pages into the book cover that I printed with a knit pattern.
... here are some pics of my sketchbook (with more pics here) :
