Interesting reading the commentary. What you do about record keeping is such a personal matter! I think you could just make up an information sheet of things about the quilt that you feel you might want to know in the future, copy it and keep one for each quilt in a notebook or your computer.
I give most of my quilts away, and have a poor memory, so I decided to keep a scrapbook of my quilts, so I could remember them or share with an interested other quilter. I include pics and notes about the process, unusual problems or interesting discoveries-whatever sticks out in my mind about the quilt, such as what I named it, a pic of the label, samples of the fabrics, names and pics (if possible) of recipients, thanks yous, etc. I am not too technical, so I don't feel the need to give that kind of detail, unless something unusual is involved. I do enjoy reviewing my pics once in a while, when I am ready to remember and re-enjoy my work.
