Gusset instep help for Purl Soho Stocking

Knitting https://www.purlsoho.com/create/2009/08/24/mary-lous-holiday-stocking/
And having trouble deciding what the pattern is saying in the Heel Gusset section when it says “turn work and purl back”.
How far back am I purling? To the marker? Or all the way across the row?

I knit this in 2009 and didn’t have any trouble but am stumped now!?!
Thanks for any help!

I figured it out! Peeked at the other stocking I made and realized beginning of the row shifts to the start of the instep. :blush:

Welcome to KH!
That’s the best way. Glad you have it sorted out.
