A skein of Knitlob’s Lair Tuulen tytär has 400 m / 100 g, not 500 m / 100 g. So the yarn requirement is actually about 370 m.

Quiet Folly

There were three incorrect stitches in the chart on first version of the pattern:
Row 23, st 51 is k1tbl, not k1
Row 46, st 40 is p1, not k1
Row 56, st 29 is p1, not k1

There is now a corrected version of the pattern available in Ravelry.
