Yesterday I was handed a lovely gift by a very thoughtful lady. She had been given it, the author having passed away, and wanted someone who would appreciate it to have it, for it to go to a good home. I have spent lots of time admiring it already, looking through the pages and reading the hand-written notes. This was, essentially, somebody's notebook on crochet, with all of the samples carefully attached and each stage meticulously annotated. It starts with the basics, and works it's way along to full patterns.
I wouldn't be able to guess at the age of it, and despite the loose pages and dog-eared corners, it is a precious thing.
