I use all medias for quilting, I like books the best, as I can refer back to a project specific page and refresh my memory. I have files of patterns that I have printed out from the internet, and I use them also. But nothing beats the tactile enjoyment I get from holding a "book", and "feeling" the quilt pictured with my fingers. I am lucky that book cases are in every room in this house (lots of thrift store finds).
