Why We Clean Every Curtain Before Shipping

Because every detail matters — from the fabric to your family’s well-being.

1.Hidden Dust from Production

Even new fabrics gather fine dust during crafting, so every curtain is deep-cleaned before delivery—fresh, safe, and ready to hang.

2.Preventing Mites from Fabric Transitions

From factory to home, fabric faces changing conditions—our pre-wash process removes mites and ensures every curtain arrives fresh, clean, and family-safe.

3.Curtains Naturally Attract Dust Daily

Curtains naturally collect dust, so we pre-wash every piece—removing factory residue and giving your home a truly fresh beginning.

4.Avoid Odors Before They Begin

Untreated fabrics hold odors and moisture, so we deep-clean each curtain—removing residues for a soft, fresh finish that’s ready to hang instantly.

5.Safe for Kids Who Love to Play Around Curtains

Kids love hiding behind curtains, so we make each one spotless and allergen-free—safe, gentle, and ready for every family moment.

How to Measure Curtain Sizes

Rail Width

  • If you have a curtain track already, please upload its width (excluding the rod head);
  • If you don't have one, measure the desired curtain fabric width—usually the window frame width plus 16-20 inches.

Drop Length

  • The curtain fabric height typically extends 8 inches above the window frame;
  • For Pleated style, measure from track ring to floor; For Grommet & Rod Pocket, measure from rod top to floor.

Design Details

Refined Stitching

Crafted with precise quilting, each curtain features a smooth, elegant texture. All seams are flawless — no loose threads or uneven lines, reflecting true quality.

Wide Hemline

The extended hemline enhances the curtain's weight, drape, and overall sophistication - every detail designed to look more premium.

Button Design

The button design keeps curtain edges from fipping outward and helps layers stack neaty, creating a graceful, refined drape.

Pre-Installed Hooks

We've already attached every hook by hand, so your curtains arrive ready to hang. A small detail that saves your
time - because effortless beauty should be truly effortless.

Elegant Pinch Pleats

Our luxurious curtains feature carefully crafted pinch pleats for a refined, flowing silhouette. Each fold drapes gracefully, enhancing elegance and opulence in your space.

Memory Shape Training

Our curtains use memory-setting technology to maintain perfect folds and smooth drapes, creating an elegant, full-bodied silhouette that exudes luxury.

FAQs

How Do I Choose the Right Curtain Size?

Measure Your Curtains →

For curtains installed on a track or curtain rod, we recommend measuring from the bottom of the track or rod to the floor to determine the finished curtain length.

For the best fit, please refer to our detailed Curtain Measurement Guide → for guidance on measuring width, length, and installation height.

Not sure which size is right for your space? Contact us anytime. Our team will be happy to review your measurements and help you choose the right curtain size for your windows.


Is the Price for One Curtain or a Pair?

Our curtains are priced and sold by the panel. A quantity of 1 means you will receive 1 curtain panel.

If you need a pair of curtains for one window, simply select a quantity of 2.


Can I Trust the Colors Shown in Your Photos?

Colors can look slightly different depending on lighting, screen settings, and the environment where the fabric is viewed. For this reason, the color shown in product photos may not look exactly the same as the actual fabric.

If you’re unsure about a color, we recommend ordering physical fabric samples before placing your order. This allows you to see the actual color and texture in your own space and feel more confident about your selection.

What Is Memory Training?

Memory training is a finishing process that helps curtain fabric form and maintain its intended folds and pleats. It gives the fabric a lasting “memory,” helping the curtains hang more neatly and keeping the pleats looking defined and consistent over time.

This process is especially helpful for pleated curtain styles, creating a more polished and refined look whether the curtains are open or closed.

Learn More About Memory Training →


Is Memory Training Suitable for All Curtain Headers?

Memory Training is available for most of our curtain header styles, including:

  • Pinch Pleat – Double
  • French Pleat – Double
  • Pinch Pleat – Euro
  • Triple French Pleat
  • Triple Tailor Pleat
  • Grommet Top
  • Pinch Pleat + Back Tab
  • French-Style Ruffled Top

However, Memory Training is not available for Flat Panel or Rod Pocket curtains. These styles are designed to hang naturally without permanently setting the fabric into a specific pleat pattern.

If you’re unsure whether Memory Training is suitable for your selected header style, please feel free to contact us before placing your order.


Should I Consider Stacking Width When the Curtains Are Open?

Yes. When curtains are fully open, the fabric gathers to the sides of the window, creating a stacking width that takes up part of the rod or track.

As a general guideline, the stacking width may be approximately 20% of the total curtain width. We recommend taking this into account when choosing your curtain rod or track length, especially if you want the curtains to clear the window opening as much as possible when fully open.

For help with your measurements or installation setup, please feel free to contact us.


Do I Need to Purchase Pin Hooks for a Pleated Style?

No. Curtain hooks are included with your curtain order, so you do not need to purchase them separately.

Curtain rings are sold separately and can be purchased based on your curtain rod and installation needs.

Curtain rods, tracks, rings, and other hardware are not included with the curtain order unless otherwise specified.


When Is a Double Width or Seam Required?

The maximum curtain width that can be made without a vertical seam varies depending on the curtain style, fabric, and finished length.

For specific width and seam requirements, please refer to the product page of the curtain style you are interested in. If your requested size exceeds the maximum width available without a seam, a double-width curtain with a vertical seam may be required.

If you are unsure whether your desired size will require a seam, please contact us before placing your order. We’ll be happy to help confirm the appropriate construction for your curtains.


What Is the Maximum Curtain Size for Memory Training?

  • Maximum Width: 340 inches
  • Maximum Length: 157 inches

Curtains that exceed these size limits are not eligible for Memory Training.

If you have questions about whether your curtain size can be customized with Memory Training, please feel free to contact us.


How Do I Choose a Curtain Header Style?

The right curtain header style depends on your preferred look, installation method, and how you want your curtains to hang.

Each header style creates a different appearance, from classic pleats to a more relaxed and modern look. We recommend reviewing our detailed guide to compare the different options and find the style that best fits your space.

I’m Purchasing Curtains for the First Time. Which Collection Should I Choose?

If you’re purchasing curtains for the first time, we recommend choosing a collection based on your preferred style and the atmosphere you want to create.

My windows are domed / pointed / fan-shaped / irregular, how should I design (the curtains) for them?

Due to the higher measurement requirements for irregularly shaped windows and sloped ceilings, you can send photos to our email at support@threegirls.com, along with your ideas. We will also design multiple solutions for you to choose from and guide you on which parts to measure.


How do I choose the right curtain length for a floor-length or puddled look?

Measure the distance from the bottom of the curtain rod (or rings) to the floor, then choose your preferred length:

Hovering above the floor: Subtract about 1–2 inches from your measurement.

Touching the floor: Choose a curtain length that matches your measurement.

Puddled on the floor: Add extra length to create a soft, relaxed drape.

The final look may vary depending on the fabric weight and curtain style.


Do you have any tips for installing a curtain rod?

Mounting the curtain rod close to the ceiling (rather than right above the window frame) is a classic trick to enhance the visual sense of space in a room.

The core principle is to guide the eye upward through vertical lines, making the room appear taller and more spacious visually.


Light-filtering VS. blackout curtains. Which one should I choose?

Typically, light-filtering curtains are installed in living rooms and dining rooms to ensure ample sunlight. Blackout curtains are used in bedrooms for sound insulation, noise reduction, and to guarantee quality sleep.

Of course, if you’d like, you can install double-layer curtains: a sheer layer plus a blackout layer. During the day, you can use the sheer curtains to block visibility, and for afternoon naps, the blackout curtains can create a completely dark environment, so that your sleep won’t be disturbed by light.


Do you offer fabric samples?

Yes, we offer free fabric samples to help you choose the right fabric and color before ordering.

You can request samples here→.


I want to design a layer of sheer fabric plus a layer of curtains, how should I make this happen?

You will need to purchase a set of sheer curtains, a set of blackout curtains, and a set of double-track/double-rod curtain rods.


Why does the color of the curtains seem fine when I receive them, but they look like a completely different color once hung up?

When you receive the curtains, the color looks normal, but once hung up, it seems as if the color has changed. The core reason is the difference in observation environment and fabric state leading to changes in visual perception, not an actual color deviation of the curtains themselves:

First, the difference in light environment: When received, the light source is single and the fabric is folded or laid flat; once hung, the curtains are in an open space, and the mixed illumination of natural light or indoor lamps, even the reflected light from outdoor scenery, will alter the color presentation.

Second, the impact of fabric form and background: When folded, the fabric is smooth; when hung, folds create light and shadow, making the color appear darker or uneven. Additionally, when the curtains are installed next to walls or furniture, the background color sets off and amplifies tonal deviations.

The color perception of small pieces of fabric is weak, but when hung as a large area of color, subtle tonal differences become prominent, ultimately making people feel “the color has changed.”


Why do some custom curtains have a maximum length limit?

Some printed or patterned curtains may have length limitations because longer curtains may require multiple pieces of fabric to be joined together. This can affect the pattern alignment and overall appearance

To ensure the best finished look, certain fabrics may have a maximum length limit. If you need a longer length, please contact us and we’ll help you find the best solution.


Which curtain heading style is the most popular?

The most popular curtain heading style is the Pinch Pleat - Double, and we always recommend choosing this one. It glides smoothly when opening and closing, with relatively little impact from friction.

Additionally, this heading style is compatible with both standard curtain rods and tracks, making it suitable for a variety of scenarios.
