Step One shows you the location of the Yarn in front of the stitch on the left needle.
Step two slip needle into stitch from right to left.
Wrap the yarn by pointing tip of right needle around the yarn and pull through left to right.
These are the four steps, and just between step 3 and 4 I removed the stitch from Left needle t right. Got my hands out of the way to just show needles and yarn.
