Bibd off

What bind off would you use for a blanket ending in seed stitch?
Thank You

I would BO in pattern.

But, it depends on how concerned you are that the BO edge look like the CO edge.
And, whether or not your BOs turn out tight, in which case you may want to use a larger needle or stretchy BO to avoid gathering/bunching of the BO edge.

Agree. I’d bind off in pattern.
