as these should remain straight so
that the pattern piece grainline is not
altered. See diagram 6.
If you need to add more than
1.5cm (5/8in) to each hipline seam,
you should use the ‘box-and-slide’
method to adjust your pattern. This
method allows you to add in a greater
amount of ease with less pattern
distortion. Simply box out the area
to be adjusted, slide out then blend
in the outer edges of the box to the
original seams of the pattern. More
than one box can be used to add
greater amounts of adjustment. See
diagrams 7 and 8.
The Swayback: There is a high
probability the hourglass fi gure will
have a swayback curve. This is repaired
by slashing into the centre-back
seam of the paper pattern below the
waistline curve, creating a pivot point
at the side seam. The upper pattern
section of the cut is moved downwards
by the required amount (generally
between 1cm and 2cm [3/8in and
3/4in]) to eliminate the ‘swayback
buckle’ without changing the waistline
shape. It is always important to
move the upper piece downwards to
avoid changing the grainline of the
bottom section of the garment. The
soft fullness at the waist or the ‘soft
square’ waist suitability camoufl ages
the presence of a swayback curve.
