It was one of the most difficult projects I knit…
Knitted it back and forth it about ten times, trying to mirrore the charts, calculate the heel, gusset dec. and the toe dec.
Basically I only took a the chart from this pattern and did my one calculations.

Notes to myself:

German twisted C= 80 sts. om 2.0 needles

Ribb 20 rows
Pattern om 2.5 mm needles.
Added 1 row white after rows 3 and 36.
Mirrored zickzack chart to get rombs after row 23 ( +8 rows).
Heel:
On 2.0 mm, added 1 st. for symmetry. Reinforced heel om 41 sts and 36 rows.
Slipped stitches from the purl side = row 1.
Heel turn:
16 - 9 -16
Picked up 19 and 20 sts along the side of heel.

Gusset:
Started row at the middle of foot ( middle of the pattern) Dec. on needles 1 and 4 2-nd and 3-d sts. every second row.

Toe:
Dec 3 and 4 sts in 1-st needle and so on.
2 times every 3-d row.
Then every 2-nd row until 12 sts/needle, then every row until 6 sts/needle.
