2. Introduction:-
Pattern making is an art. It is the art of manipulating and creating flat
pieces of fabric to match one or more curves of the human figure.
Pattern making is a bridge function between design and production. The
sketch can be transformed into a garment through a pattern that explains
the design clothing material form.
Objectives:-
To learn about pattern drafting.
To learn how to create a pattern for trousers.
To learn measurements for different parts of the trousers.
To create a pattern according to standard body measurements.
Tools and Equipment:-
Measuring tape.
A set square and protractor or pattern master.
Hip curve.
Steel rule.
Pencil and eraser.
Pattern paper.
Required Measurements:-
Waist.
Hip.
Upper thigh.
Crotch depth.
Trouser length.

4. Working Procedure:-
1. Take a pattern paper and divided it into two parts. Then draw the total
length of the trouser A to B. A to B total length is 34".
2. From A, mark out the Crotch depth point C+ 0.25" vertically. Here A-
C=9". Square out the point C to the left and right. Then take one third of
measurement from C towards A. And label this point D. Square out the
point D to the left and right. C-D= 3".
3. Mark out the back hip (C-E) and front hip (C-F) measurement from C
and label this point E&F.
Back hip=[hip/4]+.25"= [35"/4]+.25"=9"Front hip=[hip/4]-.25"=
[35"/4]-.25"=8.5"
After taking hip measurement, Connect the lines on back D-G & A-I
which is same as C-E. On the Front line D-H & A-J is same as C-F.
4. Mark the middle of the vertical lines I-E at the back and J-F at the
front and label them K & L.
5. Back Crotch extension: Taken half the back hip measurement, taken
from E to outwards and label M. E-M=4" front Crotch extension. Taken
the quarter Front hip measurement, taken from F to outwards. And label
N.F-N=2.25".
6. Mark 2" lines at Angle 450 from E. Then draw the crotch touching M,
the 2" & K. Mark 1.5" lines at Angle 450 from F. Then draw the crotch
touching N, the 1.5" & L.
7. From I, mark 0.75 inch inwards & label as O. From O, mark the back
waist 7.5"+2.25". 2" for the dart & 0.25" for the ease.
5. 8. Find the midpoint & draw the 2" wide dart with a length of 3" and
connect the dart length also connect K to O with a line.
9. Raise O by 0.25", above the waist line and connect back to the waist
mark with a slant line. And connect the waist mark to the hip using
scale.
10. From J, mark the front waist measurement+1.25" horizontally and 1"
for the dart. Find the midpoint and draw in the 1" wide dart.
Front waist =[waist/4]+.25"= [31"/4]+.25"=8".
11. Then Lower J by .25" and draw a line linking J to the waist mark on
the top line.
12. Mark the knee point and square out P=[C-B/2]-1=[30/2]-1=14"
13. Mark the midpoint of M-C & C-N and connect to the bottom line.
14. And the bottom of the trouser Front side, Mark the trouser line in left
2" and right 3". Connect N to the line and also connect out seam to hem.
On the Back part,
Also connect M to hem and out seam to hem.
All the operation is done and cut the front and back part.
6. Conclusion:-
After completing this experiment it is known how to measure body for
trouser pattern. It’s also known from this experiment how to make
pattern for trouser. Finally we gain practical knowledge from this
experiment which will be effective for our job life.
