Step Five

So now you've wrapped 7 stitches on each side of the heel and have finished with a purl row.
Next row, knit to the first wrap.

Pick up the first wrap by slipping your right needle under the wrap

At the same time, insert your needle into the next stitch, slide it off onto your right needle and..

Knit them together as one.

Turn your work and slip the first stitch purlwise (this is the stitch you just made when you knit the wrap and its stitch together).

Purl to the first wrapped stitch. Pick up the wrap by inserting your needle from the back (or from the knit side) and place it on the left needle.

Purl these two (the wrap and the stitch) together.

Turn your work.

Slip the first stitch on your left needle purlwise (again, this is the stitch you just made when you purled the wrap and stitch together).

Continue knitting/purling across back and forth, picking up the wraps and knitting them together with their wrapped stitch as you have done, until all stitches have been worked, ending with a knit row.

You'll have a turned heel!

Now slide sock A off to the side, and do the same for Sock B, using the appropriate ball of yarn of course!
