QuiltE, I like your idea of highlighting the outer line for an alert.
I will be using colored pencils to color code my sections. I have also used word codes if I am using similar colors but different prints. Like: bl/wh big dots; bl/wh stripes. It takes a little longer but keeps me from getting turned around.
Mirabs, don't feel alone. I will help you keep up the back of the line. We just returned from my Aunt's memorial and I have an Uncle and a dear friend in the hospital so I haven't been able to start yet either, let alone pick out my fabrics. We will get 'er done though!!!!
