A curved satin-style detail can create a different stitch arrangement along its inner and outer edges. The local result deserves attention even when the overall shape looks correct on screen.

Inspect the relevant region
For a curved mouth, review the actual inner edge and nearby junctions. A broad stitch-count total does not reveal where stitches concentrate.

Ask for a controlled comparison
Have the digitising specialist evaluate an appropriate adjustment on the intended material. Preserve the changed setting and resulting sew-out. The useful outcome is a specific improvement to the observed detail, not a universal rule that every curved feature needs the same treatment.
