Alternating Squares Slippers

I use to have this pattern, so I would be interested in it too. I know that it is somewhere in all of my loose patterns, which could be in one of three rooms. I learned it when I was a teenager (40 years ago) I carted it back and forth, home to home, Washington to Alaska and back and forth. I know I have seen it since I moved here, but my daughter wanted me to teach her to make it and I couldn't find it. so if someone has it, I would like it to. I remember it starts with the 2 rows of color A, which does not change, then six in the color b, then six in the color a, but I can't remember how many to cast on, or what to do for the lower part of the foot. I am probably missing some steps. There was something that made it crease I think. Grama use to make them for the whole family. So, I too would like the pattern.
