How do you read a commercial pattern and lay it out correctly to cut the pieces of an item?

Working with a commercial sewing pattern: reading the pattern envelope and instruction sheet, understanding pattern markings (grainline, notches, darts, fold line, cutting lines), and laying out and cutting pattern pieces correctly on the grain.

A focused answer to the SQA National 5 Fashion and Textile Technology content on pattern work, covering the pattern envelope and instructions, the meaning of pattern markings such as grainline, notches and fold line, and how to lay out and cut pieces correctly on the grain.

What this dot point is asking

The SQA wants you to read a commercial pattern (the envelope, the instruction sheet and the markings on the pieces) and to lay out and cut the pieces correctly on the grain. This is a key practical skill, and the question paper tests your understanding of pattern markings and correct layout.

The pattern envelope and instruction sheet

Pattern markings and what they mean

Laying out and cutting on the grain

Try this

Q1. State what the grainline arrow tells you to do. [1 mark]

  • Cue. Place it parallel to the selvedge so the piece is cut on the straight grain.

Q2. What does a fold-line marking on a pattern piece mean? [1 mark]

  • Cue. Place that edge on the fold of the fabric and cut the piece as one symmetrical whole.

Q3. Explain why you should follow the recommended cutting layout on the instruction sheet. [2 marks]

  • Cue. It uses the fabric economically and keeps every piece on the correct grain, so there is enough fabric and nothing is cut wrongly.

Show worked answer →

Award up to 2 marks for each marking explained, to a maximum of 4. The grainline arrow shows the direction the piece must lie on the fabric; the arrow is placed parallel to the selvedge so the piece is cut on the straight grain, which makes the finished garment hang correctly and not twist or stretch out of shape (up to 2). Notches are small marks on the cutting edge that show which pieces match up and how they fit together; matching the notches when sewing makes sure the pieces are joined in the right place and the right way round (up to 2). Markers reward the function of each marking, especially the grainline keeping the piece on the straight grain.

SQA-style Explain4 marksExplain why a pattern piece must be placed on the straight grain and why the layout on the pattern instruction sheet should be followed.
Show worked answer →

Award up to 2 marks for each reason, to a maximum of 4. A piece must be placed on the straight grain (grainline parallel to the selvedge) because the grain is the strongest, most stable direction; if a piece is cut off-grain the finished garment twists, sags or stretches out of shape and does not hang correctly (2). The recommended layout on the instruction sheet should be followed because it positions all the pieces to use the fabric economically, keeps every piece on the correct grain, and places pieces on the fold or cut twice where needed, so there is enough fabric and nothing is cut wrongly (2). Markers want the grain reason linked to hang/shape and the layout reason linked to economy and correctness.
