Design and make your own curtains will save you a lot of money , considering how easy it is to do. You can buy cheap fabric and a wide variety of fabrics available almost everywhere. Department stores now have a large selection of items for crafts and sewing, so you can be as creative as you want. You’ll have to know how to calculate the amount of fabric you need to buy, but that’s a simple procedure.
Measure your windows side by side or horizontally, including frames. For a curtain with many folds and much coverage , this measure will be half the size of a panel. You’ll have to do two panels for each window. For example, if your measure through the window is 36 inches (91 cm), and that is half the size of a panel, duplicate it and have 72 inches (1.83 m) for each panel.
Take the measurement from the side top of the window frame to the lower window sill. Add 10 inches (25 cm) on the top for seams and hems, and whatever you want to the bottom, depending on how you want the curtain to hang below the window. For example, if the window is 60 inches (1.52 m), add 10 inches (25 cm) on the top and, for example, 12 inches (30 cm) at the bottom, so the total length would be 82 inches.
Determines how many panels you need two for each window. Now multiply inches long, 82 (2.08 m), as explained in step 2 by 2 and you’ll know you need 164 inches or 13.6 feet or 4.5 yards (4.17 m) for the long two panels per window, according to our example.
Look at the size of the width of each panel. In our example, was 72 inches (1.83 m), which is higher than the normal width of 45 inches (1.14 m) Fabric is sold by the yard. This means that instead of a length, you’ll get twice the amount of yards you got for the length of step 3. (Two sections of 45 inches [1.14 m] will give each 90 inches wide [2.29 m], which is more than enough for the 72 [1.83 m] we obtained in this example). If your windows are very large, perhaps you may have to triple the amount.
Concludes by multiplying the number of yards you got for the length of step 4 by the number of widths obtained in step 5. In our example we have 4.5 yards (4.11 m) multiplied by 2 means that we will need 9 yards (8.23 m) of fabric for each window. This number can be adjusted when you understand the formula for the width of each narrower or wider panel.
