For those who downloaded the pattern prior to March 2013. The pattern has since been corrected and the current PDF reflects those changes.

Errata for Heel flap (Linen Stitch Heel): worked back and forth over 35 stitches.

Adjust stitches so that top of foot has 37 stitches, two diamond rib repeats with p5 between them, and p3 on either side. Heel flap should have two diamond rib repeats with p5 between them, plus p2 on either side.

Row 1 WS: Sl 1 purlwise, (Sl 1 wyb, p1), repeat from, end p2.
Row 2 RS: Sl 1 purlwise, (* k1, Sl1 wyf), repeat from , end k2.
Repeat these two rows 16x, with total of 32 rows for heel flap, or until flap measures approximately 2.25 inches. Insert additional repeats for a longer heel.
