Cosishade is the light-filtering half of a pair at New Blinds, the daytime answer to the blackout Cosibloc. The construction is the same pleated honeycomb (or cellular) cloth that folds into its own air pockets, and it is sold the same no-drill ways: as a stick-on blind and in the clip-in perfect fit format, with a Dlx tier above the standard line. The word Privacy turns up in the variant names, which tells you the job - screening a room while keeping it bright, rather than blacking it out. There are 24 colourways from £50.70, and it is a New Blinds exclusive among the retailers we track.
Who it suits
This is the blind for the window you want softened, not sealed. A light-filtering cell diffuses daylight into an even glow, breaks the sightline from the street, and keeps a room usable and bright at the same time, which makes it the natural pick for living rooms, kitchens, home offices and any ground-floor window facing a neighbour. The two no-drill make-ups then sort buyers by window: the stick-on version mounts to the frame with adhesive and suits a shallow reveal, while the perfect fit version clips into the beading of a uPVC pane and lifts out without a mark, which our perfect fit guide covers in full and which renters and tilt-and-turn windows both favour. There is a bonus in the construction, too: the same honeycomb cells that soften the light trap a layer of still air against the glass, so a light-filtering cellular blind still lends a hand with warmth and draughts. What Cosishade is not sold as is a blackout - for a bedroom that must go properly dark, its sibling carries the coated cloth.
The colours
24 colours available
The palette is quiet by design, because a privacy cloth is bought to defuse a window rather than to decorate it. The pale, light-giving shades lead: Ivory Cellular and White Cellular for the cleanest schemes, with the warmer Brown Honeycomb and the sandy Dune Honeycomb for rooms that want a little heat in the tone. At the dark end sits Black Cellular Privacy, whose name spells out the whole point of the range. As with Cosibloc, the construction is written into the shade names - Cellular and Honeycomb describe the same pleated, air-trapping cloth - so the label tells you how a colour is built as well as what it looks like. A light-filtering cloth is exactly the sort whose character shifts with the light behind it, reading brighter on a sunny wall and softer on a dull day, so order samples and hold them against the actual glass before choosing.

The from-price belongs to the smallest standard make-up. The perfect fit version and the Dlx tier are their own listings with their own arithmetic, the clip-in frame forming part of one and the heavier cloth the step up in the other, and width and drop climb the figure from there in the usual made-to-measure way. Read the table above at your own measurements, and make sure any quote names the make-up you actually want - stick-on, perfect fit or Dlx - since the same shade appears in more than one listing and they are not priced alike.
How it compares
No price check across shops exists here: Cosishade is a New Blinds exclusive among the retailers we track, which cuts both ways in the usual manner - nothing to haggle against, but a light-filtering honeycomb in two no-drill formats with a premium tier is not something the identikit catalogues carry. The comparison that counts sits in the same shop. Cosibloc is the blackout sibling, the same cellular construction and the same stick-on and perfect fit make-ups wrapped around a coated cloth that stops the light rather than softening it. Divide the house between them by job: Cosishade for living spaces that want daylight without an audience, Cosibloc for the rooms that sleep. Against a plain roller of similar opacity, Cosishade adds the insulating air layer a flat panel cannot, and folds away far tidier than a slatted blind; against a heavier voile or dress curtain, it gives the same soft light with none of the bulk.
A note on care
Cellular cloth asks for a light touch and no crushing. Run the vacuum's soft brush along the pleats on a low setting, working with the folds so the cells keep their shape, and lift marks with a barely damp cloth and a little mild detergent rather than soaking, which a pleated cloth holds and dries slowly. Raise and lower the blind from time to time so the folds sit evenly and no crease sets in. The perfect fit frames unclip for cleaning the glass behind them and reseat by hand, so check they sit square as you go, and keep an eye on any adhesive mount to be sure it still holds true. Kept dry and handled gently, the honeycomb keeps its crisp, even folds for years.
