I discovered they were coming from the book sitting there. I pulled out the book several months ago to look up a photo of a house in Portland that someone on the QuiltArt list had used as a subject for a quilt and it has been on my desk since then.
This is the book.
I love this book. It was given to me as a thank you gift when I retired as Chair of the Ashland, Oregon Historic Commission. It is the history of architectural styles in Oregon and filled with great photos. Everyone on the Commission signed it and it is a great memory of a time in my life that I really enjoyed.
When I opened it up I could see that the glue binding has crumbled and the whole book is about to go to pieces. Oh dear. Does anyone know how to repair a book that is in this condition?
