Anael and QNSue ... are your notes in your books, the changes or tricky things about the quilt block? or more about what is happening in your lives as you make the blocks? or your personal reminiscences as to memories the blocks made you think about? Great idea to do all the notes.
My books have the dates I completed each block and then number of pieces .... nothing else though. And no way I would get rid of them. Aside from the stories in the books, I see them as an incredible resource to use when looking for different blocks to make.
A few years ago, I bought a perpetual calendar with a block every day. It's kind of fun to turn the page each day and see what the next block is. I've often thought it'd be fun to make each block in the calendar, doing it one block per day! Maybe some day? ... or perhaps that'd be some year?
