Lesson 7 : Construction Process

Flat pattern method

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.

Tools Required:

1. Measuring tape.
2. Brown sheet.
3. Sharpened pencil.
4. French curve.
5. Ruler
6. L scale
7. Drafting table of suitable height and width

Merits

1. Flat patterns are widely used for mass production of garments since the patterns are made as per standard sizes
2. With the basic pattern at hand, it is possible to quickly make new designs as per fashion demands.
3. The size of the developed design will be same as that of the original basic sloper
4. Grading of the basic pattern to different sizes can be done very easily
5. The basic pattern or sloper can be used again and again to develop several designs.
6. From the basic pattern it is easy to alter patterns as per individual requirements.
7. It is possible to restyle old and out of date pattern

Demerits

• Knowledge of basic principles of pattern making and pattern manipulation is necessary to make a basic sloper/pattern.
• Since it is a 2D method, it is difficult to imagine the final outcome of the completed garment.
• Flat pattern making requires professional training and one need to perfect the art.
