I've bought a lot of quilting books over the years but I won't say there were a complete waste of money because I enjoyed reading them at the time. I recently went through all my books and took bags and bags of craft books to our local library. And I took several bags of books to a English Paper Piecing class I teach and told all the students they couldn't leave without taking some books/magazines. Nothing was left. Good feeling to see others enjoy what you no longer need. And my bookshelves look amazing.
