I Faked the Custom Look Using Ready Made Blinds (And Saved $800)

I remember staring at a quote for custom Roman shades for my living room. It was $1,200 for two windows. I almost cried into my overpriced latte. That’s when I realized that ready made blinds don't have to look like they came out of a bargain bin if you know how to handle them.

• Mount outside and high to trick the eye into seeing larger windows.
• Swap plastic hardware for brass or wood pulls immediately.
• Layer with heavy linen drapes to hide the edges of the headrail.
• Choose textured materials like bamboo or woven wood over flat plastic.

Confession: I don't always specify custom window treatments

There is a persistent myth in the design world that if you aren't ordering made-to-measure window treatments from a high-end showroom, you've already failed. I'm here to tell you that’s nonsense. I’ve spent years balancing high-low budgets for clients, and blinds ready made are often the secret to finishing a room without draining the savings account.

The trick is knowing where to spend and where to save. I’ve previously made my own custom blinds when the fabric was the star of the show, but for most everyday spaces, a standard size works perfectly if the installation is intentional. It’s about the architectural integrity of the room, not just the price tag on the box.

The dead giveaway that your blinds are off-the-shelf

The biggest mistake I see is the 'inside mount gap.' People buy a standard 34-inch blind for a 34.5-inch window, mount it inside the casing, and end up with a half-inch strip of exposed glass on either side. It looks unfinished, cheap, and lets in a distracting sliver of light at 6 AM. It screams that you bought the wrong size and just hoped for the best.

Another tell-tale sign of premade blinds is the flimsy, translucent plastic material. If the sun turns your white blinds into a glowing neon rectangle, the material is too thin. You want weight. You want texture. You want something that looks like it has a thread count, not a chemical composition. Look for 200 gsm or higher in fabric shades to ensure they hold their shape.

How I fake the built-in look with standard sizes

To get that custom feel, I almost always ignore the inside of the window frame. Instead, I buy ready made blinds that are 4 to 6 inches wider than the window itself. By mounting them on the wall above the casing—usually about 5 inches below the ceiling—you create the illusion of a massive, floor-to-ceiling window.

When you pull the shade down, it covers the entire frame, hiding the fact that your windows might actually be small or oddly proportioned. By layering standard roller shades in this outside-mount style, you create a clean, boxed-in look that mimics expensive millwork. I once used this trick in a rental with tiny windows, and the guests genuinely thought I’d had the walls bumped out.

Hardware upgrades that cost pennies but look like dollars

The first thing I do when I unbox ready made blinds is throw away the clear plastic tilt wand. It’s a design crime. Replace it with a corded pull and a heavy brass weight, or a wooden wand that matches your flooring. These small tactile touches are what people actually notice when they go to adjust the light on a warm October afternoon.

Modern off-the-shelf options have come a long way. You can now find versatile day night shades that offer a sheer layer and a privacy layer in one unit. If your blinds didn't come with a valance, you can create a 'soft valance' by mounting a simple 1x4 board wrapped in matching fabric over the headrail. It hides the mechanical bits and makes the whole unit look like a built-in feature.

Why standard sizes desperately need a soft drapery companion

A blind on its own can look a bit clinical. To truly pull off the 'custom' look, you need to flank your ready made blinds with drapes. I’m talking about 100% linen or a heavy cotton velvet. The drapes should be hung high and wide—just like the blinds—to frame the window. This hides the edges of your outside-mounted shades and adds the 'fullness' that cheap treatments lack.

Go for a 2.5x fullness. If your window is 40 inches wide, you want at least 100 inches of fabric width. Let them 'kiss' the floor or puddle by a half-inch. This softness contrasts with the rigid lines of the blinds and makes the entire window assembly look like a singular, high-end design choice rather than a series of budget compromises.

The 3 times you should never use blinds ready made

As much as I love a budget win, there are deal-breakers. First: historic arched windows. Trying to square off an arch with a straight premade blind looks clumsy. Second: extremely shallow window casings where you have no choice but to inside mount, but the standard sizes don't fit perfectly. You'll end up with that dreaded gap I mentioned earlier.

Finally, if you are a light-sensitive sleeper, skip the store-bought options for the bedroom. To achieve true, pitch-black darkness, you need blackout roller blinds made to measure. Ready-made versions almost always have light leakage around the perimeter. I learned this the hard way in my guest room; after one night of 5 AM sunbeams hitting my mother-in-law in the face, I swapped them for custom tracks.

Can I trim ready made blinds at home?

Some cellular and wood blinds are designed to be 'cut to size' at the store or at home with a specific jig. However, never try to hack a standard roller shade with scissors; it will fray and look terrible within a week.

What color should I choose for a high-end look?

Avoid 'stark white.' It looks like office equipment. Go for 'oatmeal,' 'bisque,' or a warm 'greige.' These tones look like natural fibers and feel much more expensive than they are.

How high should I mount them?

If you have the space, go halfway between the top of the window trim and the ceiling. This stretches the room and makes your ceilings feel much higher than they actually are.
