A basic pattern can be prepared by one of two methods either by drafting or by draping fabric on a model (or person concerned).
Drafting is otherwise called as block pattern method. Drafting may be defined as a system of drawing patterns on paper with mechanical precision, on the basis of body measurements. This is an effective and economical method which can be learned easily. The basic pattern may be modified to develop pattern for varied styles by a technique called 'flat pattern designing'. The basic pattern should have only a minimum number of darts and it should fit the body comfortably without being tight or loose.
TYPES OF PAPER PATTERN:
There are different types of paper pattern. They are
1.Standardised paper pattern
3.Block paper pattern
2.Individual paper pattern
4.Graded paper pattern
5.Commercial paper Pattern.
Paper pattern prepared using standardised body measurements are standardised paper patterns. This method is being followed in the training and tailoring schools.
The measurement of a particular person is taken and pattern is prepared using these individual measurement. The pattern prepared for a particular person will not suit other person. These are usually done at home and some tailor shop.
Generally these are made with standard sizes with thick cardboards. These are mostly used in garment industries. The garment made out of these block patterns will fit for those who have measurements equivalent to that of the standardised body measurement. In garment industry these type of pattern will be helpful to cut bulk amount of garment in less time.
Pattern of five consecutive sizes (for eg. 30', 32', 34', 35', 38' chest size) are marked in one single pattern. The required size according to the individual body measurement is traced separately, cut and used.
The paper pattern for different designs are available in readymade forms. These patterns are called as commercial pattern. These patterns are enclosed in the envelop along with the instruction sheet. The instruction sheet will provide information about selection of fabric, preparation of fabric, marking, cutting, and steps for sewing. The front side of envelope contains front view, side view and back view of garment design along with the body measurement. While choosing a commercial pattern one must choose according to the body measurement.
