You have been reading my mind I think. I so much wish I had kept even a list and photo of my projects throughout the years. There is no way to remember them all. I would really enjoy that information now.
It is never to late to start and I recognize my need to have the information. My Mother-in-law did keep a log of who she crocheted afghans for (gifted them). It was amazing to see page, after page, after page.
Yes, I am in favor of your suggestion and recommendation.
I am going to use this post to help me know what information I want to keep in my log. Good job!
