I just have a journal that I record quilts that I have made and finished. I write a brief description, the size it was when pieced, the size it was when quilted and the size it was after the first washing and drying which I do before giving it away. I also note the kind of material (like flannel or batik) if it is not regular quilting fabric. Also noted is the type of batting and the threads used in both the needle and bobbin. I also make a note of where it went. It has been helpful to have this record especially the shrinkage info.
