Mistakes & fixes

Threads pulling loose around a cut buttonhole usually means the stitching was too loose, the fabric wasn't stabilized, or it was cut open before sewing finished. Interface the area and cut open last with sharp scissors.

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.

A facing that buckles or shows on the outside instead of lying flat inside usually means it lacks understitching or the interfacing is too heavy. Understitch close to the seam and grade the allowances.

A side seam or inseam that spirals around the leg or body instead of running straight comes from pieces cut off-grain or one layer eased more than the other while sewing. Recut on true grain where possible.

A hem edge that ripples instead of lying flat, common on flared skirts, comes from turning up a curved edge without easing out the extra fullness. Ease-stitch the raw edge and steam out the fullness before turning.
