A Master Pattern is a basic pattern that is used as the building block for all other patternmaking. Master Patterns are drafted based from a person’s specific body measurements and do not include wearing ease, or any other design elements. They are simply a representation of a three-dimensional model in two-dimensional form. Software Tailoring’s master patterns include a 0.5” seam allowance which allows the user to test the pattern upon receiving it. If you wish, the pattern can be delivered without a seam allowance.
