I started keeping track when I began quilting in 2011 and daily just write down quickly what I am doing and the time. If there is something important, it may be notes on colors, place where I got the fabric and what was completed that day. I also take pictures as I go and upload them to a folder on my computer with the name of the quilt. I start with the stack of fabric and pattern, then I take pictures every so often during the construction. Take a final picture. At the end of each year, I burn a CD with all the pictures. I also make a calendar at Shutterfly for the up coming year with the previous year's quilts by month and a few notes on each one. That way I have a picture of one of my quilts on each month. I do it when they have a great sale at the end of the year.
