The Mallory is a twilight roller blind sold by Blinds By Post, made to measure in 3 finishes and starting from £58.00. Like all day-night-style rollers, it uses two layers of alternating sheer and opaque horizontal stripes that you adjust by scrolling the fabric up or down - align the stripes for privacy, stagger them to let diffused daylight in.

Who it suits

Twilight blinds sit between a sheer and a standard roller. They work best in living rooms and home offices where you want to shift between open-plan daylighting and soft privacy without swapping blinds or adding a second layer. The staggered position admits plenty of light while obscuring the view through the window from outside; the aligned position gives a dimout effect that most people find adequate for daytime privacy.

They are not a blackout solution. Even with stripes fully aligned, some light will still pass at the edges and through the fabric itself. For bedrooms where genuine darkness matters - particularly in the lighter mornings of late spring and summer - you would be better served by a dedicated blackout roller fabric with side channels or a perfect-fit frame. Children's rooms have the same limitation.

Bathrooms and kitchens: twilight fabrics are typically polyester and should tolerate normal humidity, but check the specific care guidance from Blinds By Post before fitting in a wet room.

The colours

3 colours available

The Mallory's three finishes are Aurora, Sunrise, and Twilight. The naming is atmospheric rather than descriptive, so judge the colour cards carefully before ordering: Aurora and Sunrise both carry warm tones, while Twilight reads cooler. All three are in the same price bracket - there is no premium variant in this range. The palette is compact and cohesive, suited to neutral or lightly decorated rooms; if you need something more saturated or darker for contrast, this range is unlikely to deliver it.

Price by your dimensions

Enter your window size. We round up to the next standard size, which matches how the retailer actually quotes you.

With a from-price just above £14, the Mallory sits at the accessible end of the made-to-measure market. As with all made-to-measure rollers, the price increases with width and drop; the widget above shows how the cost scales across common window sizes. At larger drops and widths, the entry price advantage narrows, so it is worth comparing against other twilight ranges before committing if your window is particularly wide.

How it compares

Compared with a standard dimout roller, a twilight blind gives you finer on-the-fly control over how much light you let in without raising the blind entirely. If you find yourself constantly adjusting a standard roller to half-mast for daytime comfort, a day-night style like the Mallory is a more practical solution.

Against a cellular or honeycomb blind, there is no thermal contest - the Mallory is not marketed for insulation and a honeycomb blind will outperform it on heat retention. If your main concern in winter is draughty windows or heating costs, a cellular blind in the same space would do more useful work.

Within the twilight roller category, the Mallory's three-finish range is narrow. If a particular colour match is essential to your room, it is worth checking whether Blinds By Post lists other twilight ranges with a broader palette before settling on this one.

Fitting and operation

The Mallory operates as a standard chain-driven roller. Measure your recess carefully before ordering: for an inside-recess fit, blinds by post will apply a standard deduction to allow the blind to sit without fouling the sides, so measure the full recess width and let the retailer's calculator apply the allowance. For a face fit - mounted above the recess on the wall or lintel - order the blind at your desired finished width, including any overlap onto the wall you want on each side.

Child-safety requirements apply to all domestic roller blinds sold in the UK. The Mallory will include a cord-management device; confirm with Blinds By Post whether the chain is a standard loop, a breakaway connector, or a wand-operated system if cord safety is a consideration for your household.

Likely the same fabric, at other retailers

Mallory roller blinds are sold under the same name by more than one UK retailer, and the price scales identically across window sizes - a strong sign it is the same fabric from the same supplier:

  • Swift Direct Blinds from £11.00
  • Blinds By Post this page from £58.00
  • So Easy Blinds from £68.15

We match these on the shared name and an identical price curve, not an independent inspection, so treat it as likely the same fabric rather than confirmed - and check the specification and colour at each retailer before buying.
