I feel your pain -- I have a friend who has brought me so many of these that I've had to donate some to a local school. It killed me to do it - my greedy self wanted to keep them all. I made sure I kept all the faux leather ones for sure (I do a lot of general crafting as well as quilting)
Make clutch purses. Eyeglass cases. Scissor cases. Needle cases. ANYTHING cases. There is a lady online who is designing a pattern for a case for post it notes and when she posts it (cute) I will post it (using a post it?)
Many of the "upscale" fabrics are still 100% cotton and will work as quilting fabrics I have found after you wash them. The finish that made them fancy-fa-fa expensive washes off, and volia! You'll have a wonderful layer cake square. Using the coordinating fabrics you might be able to make things like bedroom slippers. (I don't know how big you books are - I have them in various sizes from huge to tiny)
Be nice to the person who gave these to you - then beg for more. Ask for the trim books too - oh my oh my oh my. It is so very nice to get the dangly trim sample books. Trust me.
