I am keeping a record of the time I put in on my white-on-white quilt, and sometimes I add thoughts to the time notations. Comments on things I have problems with, solutions to the problems, good ideas I have about making part of the project easier--stuff like this goes in with the time. I keep all these notes in a small (about 6 in. x 8 in.) "blank book" that I plan to include with the rest of the quilt documentation. The main purpose of the little book is to keep track of the time so that when someone asks me, "How long did it take you to do this?" I will be able to tell that person how many hours I spent quilting. :-)
