Constructing the Basic Trouser Block
Added Aug 9, 2009
Mark the point M to the left of point D on the knee line, the distance from point C to point L (determined in previous step), plus 1,3 cm (1/2 in.). For waist sizes between 78 cm (30 in.) and 91 cm (36 in.), add 1,5 cm (5/8 in.) rather than 1,3 cm (1/2 in.). For waist sizes from 91 cm (36 in.) to 103 cm (40 in.), add 1,7 cm (3/4 in.) instead of 1,3 cm (1/2 in.). For larger waist sizes, add 2 cm (7/8 in.) instead of 1,3 cm (1/2 in.). Keep a note of the distance between points M and D, as you will need this for the back leg block.
Draw a straight line between points L and M. Note that you should still be working on the Front Leg Panel.
On the Front Leg Panel, draw a curved line between points M and H. The largest deviation from the line between M and H should not exceed 0,5 cm (3/16 in.).
