I find chain piecing a challenge just for that reason. I usually take a picture of my design wall and keep it close so I get them in the right order. I also use something like a cookie sheet to put them on from my design wall to carry them over to my machine. Another thing that helps is to put a pin facing in the direction of the side I'm supposed to sew on. Usually one pin on the top one in the pile is enough to get me going.
