The best I do is take a picture, sometimes in process or most often at end. I do take a picture of everything I make and keep the pictures in a separate folder by year in my documents/pictures on my computer. They are dated and named but that is about it. I do back up periodically but as for the details, if my memory doesn't hold out, they are gone forever.
Gonna check out the quiltalbum app, may be easy way to get those details down.
