Mistakes & fixes

Fine, sheer fabric sliding out of alignment or getting pulled into the feed dogs comes from its light weight offering little resistance. Sew between two layers of tissue paper or use a straight-stitch throat plate.

Satin or silk sliding apart mid-seam despite pinning is caused by low surface friction between layers. Use fine silk pins or clips, hand-baste critical seams, and sew slowly with a walking foot.

Fabric clinging to itself or the machine bed, distorting seams, is caused by low humidity and synthetic fibers building static charge. A light water mist, anti-static spray, or humidifier reduces the effect.
