Next time I’ll use this yarn, I need to use smaller needles liike 2,0mm. With 2,5mm needles the fabric is too loose for my taste.

CO 64 sts. K1, p1 ribbing for 10 rows. Knit 60 rows. K1, p1 ribbing for 10 rows again. Knit 1 row.

Heel flap with 34 sts for 30 rows. French heel with 6 sts in the middle. Pick up 17 sts from both sides. Decreases on every row until 60 sts remain.

Knit for 65 rows. Toe decreases: 5 times on every other row, 6 times on every row. Use kitchener’s stitch to close the gap (16 sts).
