Presser-Foot Pressure Is a Fabric-Feeding Adjustment, Not Thread Tension
Understand what presser-foot pressure changes, how it differs from thread tension and how to test an adjustment on a useful fabric sample.

Reduce seam bulk in a collar or facing by trimming allowances to different widths while protecting the stitching and planning for the fabric’s behaviour.

Understand when a curved seam needs clips or wedge-shaped notches, and practise without cutting through the stitching.

Understand where an overlocker helps with seams and raw edges, and why it does not automatically replace a conventional sewing machine.

Recognise twill’s diagonal structure, compare it with plain weave, and avoid treating a weave name as a complete fabric specification.

Follow warp and weft in a woven sample, distinguish them from knit loops and use the information when reading fabric descriptions.

Two parallel gathering rows give you more control when distributing fabric into a ruffle and attaching it to a straight edge.

Choose bias tape by the edge you want to finish, and test the fold, width and reverse-side stitching before sewing the garment.

Use temporary basting stitches to check alignment, fit and fabric movement before sewing a difficult seam permanently.
