Gusset instep help for Purl Soho 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.
