I'm newer at quilting as well and recently created an excel document listing details that I want to preserve forever (i.e. dates, pattern name, recipient, machine, batting, fabrics, etc.) I've also taken pictures of everything and keep in a special picture folder on my computer. Lastly, I have saved the printed patterns I've used with all of my modifications and notes in a file folder/cabinet - I can see this is where organization will be a challenge.
I agree with others it's about finding what system works for you. Good luck! Look forward to seeing pics of your projects too!
