I (former teacher) started quilting when I retired 6 years ago and bought 75 page notebooks and drew a line down the middle from the top to the bottom of each page and put down the date and the time I worked that day - brief description of what I worked on each day. I have all of those notebooks and have gone back to them many times when I want to make a quilt pattern or when I bought fabric and how much. Have found them to be extremely sometimes to answer questions on the quilting board. Takes less than 5-10 minutes each day and worth it. My thoughts.
