Heel Flap Help Needed

O.k., I’m working on the class sock from Sensational Knitted Socks by Charlene Schurch and I’m a bit confused by the instructions for the heel flap.

“slip last stitch as if to purl with yarn in front (sl 1 wyif)”

I’m sure the answer is easy, I just am confused… :wall:

Thanks!

Hold the yarn to the front as though you’re purling (which you are doing anyways, right?) and with the yarn in that position, slip the last stitch from the left needle to the right, without actually purling it.

Thank you! :muah: As I figured, it was right in front of me all the time.
