- Back-tack - A few stitches taken in reverse to secure a line of stitching.
- Bar Tack - A very short thread reinforcement for points of stress
- Baste-marking - Marking with hand- or machine-basting.
- Clean-finishing - Edge of fabric turned under once and stitched. Used on edges of facings, hems, seams, etc.
- Construction stitching - Stitching, such as seams and darts, that shapes and holds a garment together (as distinct from stay-stitching, finishing, etc.).
- Crocking - Color rubbing off.
- Directional stitching - Stitching with the grain in woven fabrics. In knits, stitching all seams in the same direction.
- Ease - The allowance added to a body measurement to make a garment wearable.
- Ease, to (verb) - To attach a fabric edge to an edge that is slightly shorter. When ease-stitching, the longer edge s very slightly gathered.

- Stability - The degree to which a fabric resists pulling out shape.
- Stay - A tape added to a garment part to keep it in shape.
- Stay-stitching - Stitching done inside the seam allowance, before construction, to stabilize curved or slanted edges. Usually done on a single thickness, but also used to attach interfacing.
