I do take a photos of my quilts and special items, print them out for my quilt album and include a little bit about them, dates, etc.
I also keep an annual journal of sorts, mostly about quilting and also include stuff about family, friends, trips, addresses of people I send quilts, pillowcases and other stuff to. I keep all my fabric and book order forms in the journal and any papers that I might want to refer to at a later date. Better to have them and not need them than to hunt all over for a paper you threw out by mistake.
