Pinch Pleated Draperies
|
| Pinch pleated draperies are a popular
treatment for windows because draperies open to let in light, and close
for privacy. The pleats are spaced at intervals to control the
fullness of the drapery. The more fabric that is pleated into the
drapery panels, the fuller the draperies become.
Before you can determine the size of the drapery panels,
you must determine the hardware and the mounting. For Conventional
rods, measure from 1.3cm (½") above the top of the rod to the
desired finished length. For draperies that are mounted on
decorative rods, measure from the pin holes in the rod to the desired
finished length
Remember to include a stay back when mounting the
rods. This is the amount needed at the side of the windows for the
drapery to clear the window when the drapery is open to its fullest.
Actual stacking space will vary with the weight of the fabric, the
fullness, and whether or not the drapery is lined, but it can be estimated
at one-third the window width measurement. For center-pull
draperies, allow for half the stacking space on each side of the
window.
Cutting Directions
Measure the window,
follow the guidelines for curtains and draperies. There are two
basic measurements to consider: finished length and finished
width. Estimate meterage and cut the lengths for drapery and lining,
using the chart below. These directions are for a pair of draperies.

Drapery Pleats
Use the drapery pleat worksheet below to
determine the number and size of pleats and spaces per panel; this
should be done after panels are sewn together and hemmed.
The recommended amount of fabric required
for each pleat is 10cm to 15cm (4" to 6"). The recommended
space between pleats is 9cm to 10cm (3½" to 4"), approximately
the same abound as the center overlap. If the worksheet calculation
for the pleat size or the space between pleats is greater than the
recommended amount, add one more pleat and space; if the calculation is
smaller than the recommended amount, subtract one pleat and space.

*Figure 5 pleats per width of 122cm
(48") fabric, 6 pleats per width of 140cm (54") fabric. If
you have a half width of fabric, figure 2 or 3 pleats in that half
width. For example, for 122cm (48") fabric, 2½ widths per
panel = 12 pleats.
