BO last stitch when next step is to rejoin yarn
I need a bit of help figuring out what to do w/ my last BO stitch when the next step in my pattern has me rejoining yarn. Here's what it says:
(with 23 sts on ndl) BO 9 sts, k4 (5sts on rt-hand ndl), BO remaining 9 sts on lft-hand ndl, ending up with 5 stitches.
I get that I'll have 5 stitches left in the center of my work, but the next step is:
With RS facing, rejoin yarn to 5 sts on ndl. Cont in St st for 4"...
Do I cut my yarn when I BO my last stitch, and then add new yarn as if my skein was gone (for the rejoining to the 5 sts), or do I somehow have to keep my working yarn "working" after I bind off?
I appreciate any clarification/help/wisdom/etc !!
