I miss books not having jackets so much anymore. Slipping the jacket cover into a spot in the book always worked.
Really everything is beautiful indeed. But a tissue, a sheet of obviously unused potty paper, those annoying subscription things that fall out of magazines, even a ripped magazine or paper plate in a pinch. But for Dear Lord's sake do not fold corners. If there is any chance at all ever that this book will ever be donated do not fold corners...really please.
