hi there sewinggilly - I've seen that written in books & online. Certainly a great idea...
Re the providence issue - mine is not quite the same, but for many years, I have kept exercise books, into which I staple fabric samples, pattern/design names, date of completion & photos.
Over the years I've made my kids clothes, sunhats, bags of all types, table runners, cushions, event clothing like wedding outfits for my DD's & communion dresses.
As a result I have quite a few exercise books of stuff. It's lovely to look back & see how much I've done. And satisfying to see the different things I've taught myself to do & skills I've mastered. And disasters I've resurrected!...
I also have a 'album' in our computer of pics of my stuff, both progress pics & pics of completed item.
I put a label or marking on every item I make.
