Quiltncrazy,
I already label my fabrics, but I don't have the detail you put into it. I just use a 3x5 paper with yardage amount, and name of fabric. I decided to start adding price and date to that.
When I do start my notebook, it will be done nicely as a presentation book, showing the quilts made, fabrics used, prices for material, labor, etc and the estimated price to make the same depending on fabric prices.
I was advised by a friend today to add $20 for use of my tools such as rulers, sewing machine, etc. and she said I should make sure I add in tax and shipping charges when figuring out the price of fabric per yard. She thinks $10 per hour is way too low for labor costs, but I think it is fine. Most of the work will be done while watching the news and a movie (which is when I sew anyway). I did like her idea to just add $30 for my expertise. I'd be more comfortable with that.
