Help needed

I was shown this stitch but I’ve forgotten how to do it and the lady who showed me has since died. Does anyone here know how to do this? The pattern shows knit stitch both sides with a panel of purl over 10 stitches to the front only. Completely flat with no groove to knit side.

Thanks for looking, Jill

It looks like mainly garter stitch (knit every row) with the middle 3 sts in stockinette. The middle sts are likely slipped with yarn in back on every other row.
