Last night I turned the corner on the lace for this project.
In looking at the lace, and the sharp angle, I decided some short rows were in order. As I finished the last row of the lace, I added a wedge of garter stitches. As I knit back to the center, I shortened each row by 2 stitches. After only 2 remained, I reversed the process, until I was back to 12 stitches.
I think it blends in nicely.
