Step six

Slip one and knit across to the first wrapped stitch.

Pick up the wrap by inserting your right needle tip from the bottom to the top.

Slip it onto the left needle with its stitch.

Knit them both together.

Wrap the next stitch (one that is already wrapped once), and turn.

Slip the next stitch, and purl across to the first wrapped stitch.

Pick up the wrap and slip it onto the left needle with its stitch. (I find it easiest if I pick up this wrap from the right side.)

Purl the two together as one.

Wrap the next stitch and turn.

Slip one stitch and knit across to the next wrapped stitch. This stitch will have two wraps. Pick them both up, and knit the 3 together (the stitch and it's 2 wraps).

Wrap the next stitch and turn.

Slip one, purl across to the next double wrapped stitch, pick up the two wraps, slip them onto the needle and purl all three together.

Continue in this fashion until you've picked up all wrapped stitches and knit all heel stitches.

The double wrapped stitches prevent holes along the heel. This is an extra step that is not entirely necessary, but makes for a beautifully knit hole-free heel!
