I have made several "quiet books" out of felt (I buy by the yard and not squares ... I think the yardage is better quality) I buy extra heavy weight pellon interfacing to put in between the felt pages. I use gromments and rings to bind the book. Pinterest does have lots of cute patterns for pages. I like a variety of skills in the book ie: velcro, snaps, zipper, tying, etc. Lots of fun to make!
