Constructing the Basic Trouser Block
Added Aug 9, 2009
Construct a diagonal segment (shown in green in the diagram) from point Q, of length 4 cm (1.6 in.) for waist sizes below 66 cm (26 in.). For waist sizes between 66 cm (26 in.) and 78 cm (30 in.), set the length of the diagonal to 4,25 cm (1.7 in). For waist sizes between 78 cm (30 in.) and 91 cm (36 in.), set the length to 4,5 cm (1.8 in). For waist sizes above 91 cm (36 in.), set the length to 4,75 cm (1.9 in.).
Then draw in a straight line from point T to point V, and a curved line from point Y to point T, passing through the end of the diagonal constructed as described above.
