A made-to-measure blind cannot be returned because the colour is not what you hoped, so the few days spent on samples are the cheapest insurance in the whole purchase. Most retailers offer fabric swatches free or for a small charge, posted to your door. Here is how to use them properly.
Why you cannot trust the screen
The same fabric photo looks different on every phone, laptop and television, and changes again as screen brightness shifts. Whites drift warm or cool, greys pick up blue or brown, and subtle weaves flatten into plain colour. A physical sample shows the true shade, but it also tells you two things no photo can: how the fabric feels, and how much light passes through it. Texture and weight decide how a blind hangs, rolls and folds, and they only exist in your hand.
Test opacity at the actual window
Opacity is the biggest surprise in most blind purchases, and the window itself is the only honest test rig.
- Hold the sample flat against the glass in full daylight and look at it from inside. A light-filtering fabric will glow; a blackout fabric should let nothing through the weave itself.
- Step back a metre or two and look again, since pinpricks of light disappear at a distance but a general glow does not.
- After dark, switch the room lights on and think about the view from outside; sheer and lightly woven fabrics offer little evening privacy.
- Remember that even a blackout fabric lets light creep around the edges of a fitted blind, so the swatch tells you about the fabric, not the whole fitted result.
Check colour in morning and evening light
Daylight is cool and lamplight is warm, and many fabrics read as noticeably different colours under each. Prop the sample against the wall it will live beside, then against the floor and the sofa, and look at it in morning light, in the afternoon and under your actual lamps in the evening. Live with it for a couple of days rather than judging it in one glance. If the blind must sit alongside a particular paint colour, check that pairing across the same range of light, not just at midday.
Sample the pairings, not just the face fabric
- Wooden and faux wood blinds: if you are choosing ladder tapes, ask for the slat and tape combination you intend to order, because tapes change the look more than most people expect.
- Roman blinds: the lining alters how the face fabric looks with light behind it, so check which lining a swatch represents.
- Vertical blinds: sample the louvre fabric itself, and picture it repeated across the full window rather than as a single strip.
- Patterned fabrics: a small swatch shows a fragment of the repeat, so pair it with the full-width product photo to judge the scale of the pattern.
How many samples to order
Order your front-runner and its immediate neighbours. Whites, creams and greys sit very close together within a range, and the shade you pick on screen is often one step away from the one that actually suits the room. Two or three neighbouring shades plus one different texture is a sensible set for each window. Most retailers allow several samples per order, so check the limit rather than placing repeated requests.
Timing, and what samples protect you from
Samples usually arrive by post within days, while a made-to-measure order takes weeks, so request swatches the moment a fabric catches your eye. Once the blind arrives, keep the sample: slight batch variation can occur, but the delivered fabric should be a clear match, and the swatch is your reference point if it is not. Above all, the sample is what protects a purchase that cannot be returned for colour disappointment. Five minutes at the window with a swatch beats weeks of regret at the same window with the wrong blind.
Frequently asked questions
How do I order blind samples?
Most retailers have a sample button on each product page and post swatches to you free or for a small charge. If you cannot see the option, contact the shop and ask.
How many samples can I order?
Limits vary by retailer, but several per order is common. Order your favourite shade plus the ones either side of it, and one alternative texture, for each window you are dressing.
How long do samples take to arrive?
They are usually sent by ordinary post and arrive within a few days. The made-to-measure lead time only starts when you place the main order, so requesting samples early costs you nothing.
What if my samples never arrive?
Contact the retailer and ask for them to be resent. Samples travel as ordinary post, so the occasional loss happens, and most shops will send replacements without any fuss.
Can I order samples of patterned fabrics?
Usually yes, but a small swatch only shows part of the pattern repeat. Use it to judge colour and texture, and the full-width product photos to judge the scale of the pattern.
Will a sample show whether a blackout fabric really blocks light?
Yes, for the fabric itself: held flat against the glass in daylight, a true blackout weave lets nothing through. Light can still creep around the edges of any fitted blind, so total darkness also depends on the fitting style.
