Baby sweater

I am halfway through my first baby sweater. Just finished right front of sweater, did the bind off (did not cut yarn) I’m now stuck. Pattern says “Back - transfer stitches for back from holder onto needle. Join yarn and work even”… Does that mean I cut the yarn from my last bind off? If I do, how do I start knitting the back piece?

Once you’ve bound off a piece, cut the yarn, leaving a tail to weave in later.

Just start knitting the next piece. Leave a tail to weave in, or you can work the first couple of stitches with the main strand [I]and[/I] the tail held together as one strand to secure it a bit. Still leave a tail to weave in there as well.
