Round Heel

I used the Round Heel for James sock. Here's a close up.

James sock has 56 stitches. The heel flap was worked on 50% of 56 or 28 stitches.

To turn a round heel, the initial row is knit to 2 stitches past centre. In the case of James socks, centre was between stitch 14. I knit to centre (14) plus 2 - or 16 stitches, before making a decrease to start the turn.

The socks look good so far and are knitting up quickly.
