I have been following TAoK step by step. I'm baffled by the dart on page 85. The dart is basted, but I cannot find any mention of permanently stitching it. Once the inverted pleat is permanently tacked down on page 88, the dart becomes completely inaccessible. What am I missing?

As always I appreciate the advice I get through this forum.
