How to Select Fabric for Curtains

Before you sit down to sew up new shades, curtains or drapes for your home you need to pick the right fabric. There is a lot to consider when selecting a fabric for window treatments. You want to think about the style of curtain, the décor of the room, and the function of the window treatment. Since the color, pattern and style of your fabric is a personal choice, we’re going to focus on the more objective side of selecting fabric—the function of the window treatment. We hope this guide will help you think through the selection process and feel confident in your decision.

Let’s take a closer look at some of the considerations you’ll want to think through when selecting curtain fabric.

Natural Light: In or Out?

One of the first considerations for curtain fabric should be the amount of light the room gets and do you want to let the light in or block it out? If you want to block out light, try a heavy fabric with a tight weave or a blackout curtain fabric. You can even back a lighter fabric with a blackout fabric if light blocking is your top priority. If you enjoy natural light in your room and want to filter it, try an open weave or a sheer fabric. Fabrics with metallic elements are also great for bouncing the light around a room.

Keep Out the Cold

It’s also common to want your window treatments to provide some insulation against the cold. A heavier weight fabric with a tighter weave will be better at keeping the cold out than a sheer or open weave fabric. Blackout fabrics often features insulating properties as well. You can up the insulation factor of any fabric by adding an interlining fabric to the back of the curtains. The interlining will also protect the fabric from UV rays of the sun and add more body. 

UV Rays and Colorfastness

The sun’s rays can be really harsh on fabric. You don’t generally think about interior fabrics needing to be UV resistant, but curtains can see a lot of sunlight streaming through the windows. That’s why we recommend thinking about the colorfastness of the fabric you choose for curtains.

This isn’t an issue in every window, so you’ll want to think about your home, which direction the windows face and how much natural light they let in, and decide if this is a concern for you. In general, south-facing windows will see the most sunlight during the day.

If UV exposure is a concern, look for curtain fabrics with UV protective qualities. Solution-dyed and vat dyed fabrics will be the most colorfast and printed fabrics the least. However, you can always add a drapery lining to the back of the fabric to protect the decorative fabric itself from UV rays. Curtain lining is also great for making fabrics a little more opaque and for adding more body for fuller looking drapes.

Fabric Width & Repeat

Especially when on a budget, it’s important to consider how many yards of a given fabric your curtain project will require. Fabrics with a thinner width or large repeats could mean you’ll need to do more seaming in drapery panels and order extra fabric to pattern match.

Typically, you want to use the length of the fabric as the length of the curtain so you might need to seam two or more panels together to get the appropriate width for your window. If your fabric has a pattern, note the pattern repeat. For the best looking shades you’ll want the patterns to match at the seam point, and a large pattern repeat can mean you’ll need to order extra fabric to get a good pattern match.

    I am looking for a window fabric to use in an RV. There is a window adjacent to the stove in the RV. I am looking for a fabric that is heat-fire resident or fire-proof! I did call Sailrite to see if you sold this kind of fabric, but the rep told me there was nothing to offer. Perhaps you would consider thinking about people who are putting curtains on windows on the interior of an RV–a window that is behind a propane stove with flames!

    I look forward to hearing your suggestions.

    Please send your ideas to me!

    Thank you!

      Hi Karen,

      I’d love to get a little more information on your set up so we can help you come to a solution. How far is the bottom of the window from your stove? Have you considered using a different style of window treatment than traditional drapes?
