Making curtains is easy, but only if you know the basics Curtains are almost all straight sewing, making them an easy project for beginners. That said, there are still some basics to master before embarking on sewing curtains for the first time.
There’s a simple calculation to work out how much curtain fabric you need. First, multiply the track/pole width by your chosen fullness (eg. Pole width 150cm x 2.5 = 375). Next, divide that figure by the fabric width, which is typically 137cm (375 divided by 137 = 2.73).
If you find some really unique fabric and have solid sewing skills, homemade curtains from by-the-yard fabric are definitely a possibility. But, unfortunately, it’s probably not a budget possibility, at least, not compared to store-bought curtains already on the market.
The cheapest (and easiest) curtains to make are tab top. The panels aren’t as gathered so they use up less fabric than a pair made with header tape.
For Standard Width Panels: Finished length of curtains + 16 inches divided by 36 = number of yards required. Add 1 extra yard (or one vertical repeat of the fabric) per pair if using a large print fabric.
Most curtains require a minimum of double fullness depending on the heading and the look you want to achieve. We recommend using 2.5 times fullness to create a luxurious look. First, you will need to multiply the width of your rail by two. Divide this by the cut width of your fabric i.e 137cm/ 54”.
For most curtains, two times the raw width of the window will be the perfect calculation. However, if you are using a very sheer fabric, you may want to multiply the window width by three. And, heavy fabrics may only require 1½ times the width of the window.
Curtains and Drapes: Typically, drapes and curtains cost an average of $100 to $250 per panel. However, this can range between $7 to $1,500 overall, depending on how fancy you want to get.
