Constructing the Basic Trouser Block
Added Aug 9, 2009
Continuing on the Front Leg Panel, draw in a small diagonal, inward pointing line from both point E (green line in diagram). For waist sizes of 66 cm (26") or less, the length of this diagonal will be 2,75 cm (or 1-1/8"). For waist sizes between 66 cm (26") and 78 cm (30"), the length of the segment will be 3,00 cm (1"-1/4). From waist sizes of 78 cm (30") to 91 cm (36"), the length of the segment should be 3,25 cm (1-3/8"). Above waist sizes of 91 cm (38"), the segment should be 3.5 cm (1-1/2").
Connect points H and F with a curved line (near horizontal at H, near vertical at F) that passes through the end of the diagonal segment constructed above. If the distance between the crutch depth line and the hip line is small, you may have trouble drawing a reasonable curve. This is where you may want to slide the hip line up a centimeter (half an inch) or two, to get a little room to manoeuvre.
