I keep a running list in an excel file.....basically date and what. for example Jan 12, 2019 completed Building blocks quilt for Mom, or made Catchall Caddy for me. I always take pictures of all the sewing I do whether totes, hand bags, quilts, placemats, whatever. I keep the pictures in a computer file labeled Quilting/sewing projects and separated by year.
As for the details, well, if the ole memory doesn't kick in, and I don't remember It is OK.
This year however, I am going to try the Bullet Journal method of daily planning and hope to track a bit better. Also hope it helps me be more productive than I have been during this pandemic. Simply didn't do as much as I should/could have in 2020. But on the bright side, I have finally been able to watch a LOT of old movies and the TV shows that came on at 10pm back in the day when I worked! LOL
