In order to correctly measure the consumption of fabric on the curtains, it is necessary to define two main parameters: the length and width of the finished products in the future.
Note that the length of the calculation is done outside the bill and underscores the bottom and top of the curtains, this option will be added later. To calculate the fabric on the curtains, measure with a metal band measure the distance from the location for fixing the curtains to the ceiling foot to the desired length.
calculation of the length
calculation of width
Before you start your measurements, it's worth a curtain rod – it will have to calculate both the length and the width of the curtains in the future. Typically to the distance from the top edge of the window to the ceiling foot in the range of 7.5 to 12.5 cm, with the width of the window he must act at a distance of at least 15 cm, to be able to release the window opening of the curtains.
To bend fine when sewing curtains on the sides, it is necessary to add 10 centimeters on each side.
The consumption of fabric on the curtains of tulle made the following formulas:
Height: height curtains + replacement + bottom extension home top
In our case we have + 2.6 0.15 + 0.10 = 2.85 (m)
Width: Length x Roof List Mounting Coefficient, or in this case 2 x 2 = 4 (m).
Flow-tissue lining curtains are made using the same formula, with the only difference that, unlike the tulle made of at least two parts. Therefore, the height will be the same, but the width of the resulting need to divide by two.
