Mistakes & fixes

An armhole standing away from the body in a visible gap, common on sleeveless garments, comes from an opening cut too large or left unstabilized. Stay-stitch the edge and take a small dart at the gap.

A waistband standing away from the body at the back or sides, despite fitting at the hip, usually means the waist is smaller than the band was cut for. Take in the waistband seam or add a dart.

Blending two adjacent pattern sizes, such as a smaller bust with a larger waist, is done by tracing each size's line at the relevant area and drawing a smooth curve connecting them across the piece.
