The type of heading, the width of lower hem and the type of drapery;
that is, lined, unlined or interlined, must be considered when
estimating the yardage required. The fullness of draperies averages
about twice the width of the space to be covered.
A stiffening; such as a strip of crinoline or buckram is used at the top
to support the pleats.
_For Lined Draperies_—To length measurement, add 1″ for heading, 4″ for
hem and 3½″ for bottom hem.
_Example_—If length from top of rod is 90″, add 1″ plus 4″ plus 3½″.
This equals 98½″ for one length, or 5½ yards for the two lengths.
_For Unlined Draperies_—To length measurement, add 1″ for heading, 4½″
for top hem and seam, and 3½″ for lower hem. A 4″ wide strip of
crinoline is used at the top of both lined and unlined drapes.
If a double hem is used at the bottom, then add 6″ instead of 3½″ for
hem in either lined or unlined drapes.
_For Interlined Draperies_—To length measurement, add 1″ for heading, 3″
for top hem and 3″ for bottom hem.
When using ready-made headings for pleats, add to the length measurement
1½″ for heading and seam, and 3½″ for bottom hem.
[Illustration: _French Doors or Window_
The rod should be placed so that the drapery, when hung, covers the
glass portion of the window. Take measurement from top of upper rod
to lower part of lower rod. To this measurement, add 2½″ at the top
and 2½″ at the bottom. This allows for a 1½″ hem, top and bottom,
plus ¼″ seam allowance. The 1½″ hem is for a ¾″ casing and ¾″
heading.]
