I have been knitting the same pattern a few times now and I think I understand a mistake I made.
My pattern requires a provisional cast on to knit the lace around the chest of the jumper. Once the lace is done, I normally bind it off after the last row and, in doing this, I always find the left over of wool located at the bottom of my lace when it should be located on the top of it (rounded shell is the bottom of the lace on my design).
I think I just figured out my mistake as I believe I should bind off while knitting the last row of the lace design. Would this make sense?
One lace design is made of 22 rows and I have repeated that 13 times. I am adding a picture as it may help to see (I knitted the last row though which I think I will have to unknit now ).
Bind off so that the yarn end is where you need it to be in order to pick up sts for the yoke or the body of the sweater whichever comes next in the pattern. But if you work a provisional cast on, aren’t you grafting or working 3 needle bind off to join the lace panel in a circle? You would still want the yarn end to finish the join on the edge nearest the following pick up of sts.
There is a seam or graft visible on the back of most where the two ends of the lace join.
This one has a photo with a comment about learning how to graft in pattern for a seamless join, it’s an impressive detail https://www.ravelry.com/projects/SilverNeons/lorelei
You can post a small section of the pattern directions, so we can more easily see what it wanted, but I agree with @salmonmac and @Creations–you don’t bind off that edge separately. You’ll attach it to the edge with the provisional cast-on using 3-needle bind-off, so that you have circle of the lace pattern. I assume you’ll then pick up on one edge and work to the neckline, and pick up the other edge for the body.
