The flat pattern method is the fastest and most efficient method for developing patterns, wherein the basic block is modified to develop new and varied styles. It helps in maintaining the consistency of size and fit of mass produced garments. Pattern can be manipulated and changed through the slash-spread method or pivot method. The slash-spread technique as the name implies refers to the technique of slashing a pattern, spreading it and manipulating to generate new patterns. In pivot method pattern is not slashed but points are pivoted for new designs. A traced copy of the original working pattern is used as the original and is never altered. After pattern is slashed and spread, it is placed on another piece of marking paper. It is retraced along the new lines. The lines are then blended, seam allowance added and grain line marked. All other pattern information is added to complete the pattern for the test fit.
