The stitch on the pastel hat is a mock cable. Picture a rib of two knit stitches and one pearl stitch on each side in your head. Now picture doing one pearl, knit one and yarn over to increase a stitch and knit one and then do a pearl. You now have 5 stitches and center is a hole. If you are using straight needles, turn and knit one, pearl three, knit one. Turn, pearl one, knit 3, and then slip the first knit on the right needle over the other two knit and you have a decrease one, and pearl the next one. Turn, and knit one, pearl two, knit one. Turn, repeat from beginning and you have a mock cable.
