My husband says to me: "Who still buys books?" I say when you are a crafter its easier to turn a page or trace a pattern out of a printed book than from your computer. All of FunWithFabric.com's books are previously owned. However, it is not unusual that about 70/80% of these books look like they could be brand new, because they have never been used. Periodically there may be writing in them. They may also suffer from a little spinal scuffing from standing on a book shelf. But unless otherwise stated these books are 100% usable. Just like with fabric, where I can, I supply all the knowledge and background in the description. I cannot always tell you if it was stored in a home with pets or smoke free. I do the "sniff" test before I acquire if it smells like smoke - It gets donated or may be posted under free items.
