I do much the same as sandraB64. I also indicate when I started, when the top was completed and when the quilt was completed. I also note whether it was hand or machine pieced and quilted, patchwork or paper pieced or appliqued and/or embroidered. I keep this info on anything I make - like purses, totes, pillowcases, table runners, table toppers etc. I really enjoy looking through my 3 ring binder "Quilt Diary"s.
