folk wisdom - "Measure twice, cut once" - will come in handy in the calculation of curtains.But before you start measuring, imagine what kind of curtains you want to see on your screen.Curtains can reach sill be lower than his or go to the floor.Proceeding from this value, the length of the future will be folded curtains.Blind in the first embodiment to be 1 cm above the sill, a second embodiment will hang below the sill of 10-15 cm, and still others to avoid wear curtains should be terminated at 1 cm above the floor.The length of the
curtains need to count down from the eaves and be sure to take into account the consumption of cloth that will go to pull up the product.All measurements is better to produce a steel tape measure, not a centimeter.Roulette longer and work with it much more convenient.
next step you will measure has strengthened over the window ledge.Do not forget that the cornice should be wider than the window and act on each side at least 15 cm. Now you can start to calculate the width of the future curtains.This value will vary depending on the type of the future curtains.For standard blinds, curtains with loops or eyelets width of the cornice is multiplied by 2, pencil wrinkles or puffs require multiplying by a factor of 2.5-3.It is impossible to forget and about 10 cm on each side curtains that will go to the hem fabric on the sides.By the way, a major recurring geometric pattern would require additional expense tissue, it is also necessary to take into account in the calculation.
To illustrate, consider an example.The length of the cornice is 3 meters, the curtains will reach the floor, and their height should be 2.5 meters.The required amount of tulle fabric obtained from the following formula.Height plus hem the top, bottom hem plus = 2.5 + 0.10 + 0.15 = 2.75 meters.This value is the length of tulle fabric.The width will be the same length of the cornice, multiplied by 2, that is 6 meters.

simple length curtains will match the length of tulle, and the width should be divided by the estimated number of paintings.This means that on the one curtain, you will need 3 meters of fabric.Do not forget to add a cutting centimeters necessary to pull up the sides.
More complex models require curtains other calculations, according to their pattern.So before you start to work on them a few times re-read the instructions for making that nothing is forgotten.And remember, it is always better to play it safe and take tissue from the margin of the remaining pieces of cloth can be stitched to the table, cushion covers for cushions, but the lack of material could have been a disaster.
