That would be a wonderful gift! In my book club, some buy hardbacks and some paperbacks, but a larger number are now only buying the books electronically to read on a Kindle or iPad, so don't carry books at all! Not sure what your members do. But as for book theme fabrics, I have seen several around, and bought some from The Fat Quarter Shop and Fabric.com. Just google "book fabric" and I think you will find many.
