1) Compute dimensions of patterns according to sizes, considering stretching of material.
2) Create a master pattern for each size within a range of garment sizes, using charts, drafting instruments, computers, and/or grading devices.
3) Create a paper pattern from which to mass-produce a design concept.
4) Determine the best layout of pattern pieces to minimize waste of material, and mark fabric accordingly.
5) Discuss design specifications with designers, and convert their original models of garments into patterns of separate parts that can be laid out on a length of fabric.
6) Draw details on outlined parts to indicate where parts are to be joined, as well as the positions of pleats, pockets, buttonholes, and other features, using computers or drafting instruments.
7) Draw outlines of pattern parts by adapting or copying existing patterns, or by drafting new patterns.
8) Examine sketches, sample articles, and design specifications to determine quantities, shapes, and sizes of pattern parts, and to determine the amount of material or fabric required to make a product.
9) Mark samples and finished patterns with information such as garment size, section, style, identification, and sewing instructions.
10) Position and cut out master or sample patterns, using scissors and knives, or print out copies of patterns, using computers.
11) Trace outlines of paper onto cardboard patterns, and cut patterns into parts to make templates.
12) Trace outlines of specified patterns onto material, and cut fabric using scissors.
13) Test patterns by making and fitting sample garments.
