This time last year...........

I think it's a brilliant idea, Veggie. Everything you need to find about a particular month will be all together, no hunting out a pile of books to find which particular June you planted such and such a plant. You can easily check at the start of each month what you have done in previous years. Plus, every month you will put away the old book and be starting a"brand new" book again, so it will inspire you to keep making notes all year. I may have to do this myself, it's such a good idea. (I'm very poor at keeping up notes/diaries after the first flush of enthusiasm).
