IT WORKED!!mitered mittens how to make a tube from these units. But when it came to the heel I had to go on faith that everything would be molded to the shape of my foot. Feet are not square, yet all the parts of this sock are. Knitting is just amazing to me.
Since I had the squares from my mitered mitten study lying around, I started with those and just kept adding squares, picking up stitches from the previous square. Looking at the pictures of the slippers above told me when and where to pick up stitches to make the heel.
