I use the pins in the upper left corner or a row method and the number of pins represents what row it is. I can chain piece up to a point. I have never been able to keep a chained piece together and sew it to another string of chained pieces. It seems like something always twists. The challenge for me is to remember which piece goes on top and what side do I sew on. I do take a picture once I have things arranged on my design board. I also take things down in order and pile them on a small board to carry over to my sewing machine. I have never been able to master the zip, zip, zip sew them together fast like I see in the tutorials but that's OK with me. I enjoy the journey as much as reaching the destination.
