It is very late in Norway! But this came to my attention this evening.
There is a correction to the 72 stitch heel turn.
The correction is on Row 1:
Sl1, Knit 19, ssk, k1
I needed to create a chart to work through the stitch count, to make sure this was correct for you.
I was not alerted to the mistake from my test pool.
My sincere apologies for any inconvenience or frustration this has caused!
