Knitting w/ 2 circular needles?

I’m knitting cocoknits pleated ballet flats. I’ve picked up stitches on both sides of the soles - 44 stitches on each circular. Instructions say "uppers are worked in the round on 2 circ needles using st st. I just don’t get it. Which needle do I knit on? One needle to the other? Any help would be appreciated. I’m so stuck!!

There’s a video on the Advanced Techniques page on knitting with 2 circs in the round too.
