Okay, changing tactics. I've been to a few other sites and, despite what "Mark says", I believe I'm supposed to do the following:
start heel flap on last stitch and work "backwards" (which will take me to stitch 31)
this also means that i will purl/slip combo on my first row of the heel flap
knit the second row
rinse/repeat for desired length
Sooo, in my picture, I will start at stitch 60, which is the new back needle, and I should be good....
Am I right????
