Sycamore stitch

I recently knit slippers for my son with a cable from my Mon Tricot stitch dictionary, Sycamore Stitch. I'm not going to write up the pattern, but I thought I could at least chart the stitch pattern for people; the written instructions are my own, not a direct copy from the original. Nobody has tested these for me; please let me know if you have problems!

Key:

Right Side: knit; Wrong Side: purl
RS: purl; WS: knit
RS: slip 1 with yarn in back; WS: slip 1 with yarn in front
Slip 1 as if to knit onto cable needle, then the next as if to knit. Bring cable needle to front. Purl 2. Yarn over. Slip the stitches from the cable needle and knit them together through back loop. (Left leaning decrease.)
Slip 2 onto cable needle and let fall to back. Knit 2 together, yarn over. Slip the stitches back from the cable needle; purl 2.
RS: purl through back loop; WS: knit through back loop (results in twisted stitch)
