How to Decrease

     Move the first stitch off of the left-hand needle onto the right-hand needle as if to knit.

     Then, do the same with the second stitch.

     Insert the left-hand needle into the stitches purl-wise.

     Wrap the yarn from back to front of the right-hand needle (as seen above). Pull the yarn through both of the stitches (therefore knitting them together) and you will have one stitch on your right-hand needle instead of two.

     This is abbreviated SSK (meaning slip, slip, knit).
