I buy the book(s)so I can look through them over and over and over again. Even if I don't plan to make all the quilts they are so beautiful to look at. I get a very small retirement check from a place I worked years ago and consider that my book and magazine money. Since it is already set aside for that and since I don't spend it for that all the time, it doesn't seem frivolous to buy something I enjoy reading just for pleasure.
