Hi folks! I love honeycomb blinds (also known as 'cellular blinds') but they aren't well-known really. Basically they are blinds where the fabric makes air pockets (like a vertical honeycomb) and this non-moving air is effective insulation.
I've been looking at a bunch of shops selling them and the prices I'm seeing from Veneta right now are unparalleled. The next-best prices would probably be IKEA but it sounds like the Veneta ones are easier to get to a custom-size and they have a better variety of sizes and lengths (and you can choose between light filter or block-out).
Hard to go wrong with this deal I reckon. If your window is smaller than the width described, apparently you can take a total of 150mm off any blind so you could buy a 60cm blind and put it in a 55cm window slot. Check out https://www.youtube.com/watch?v=6FVNb7esUKQ
For these blinds to be most effective they should sit inside the reveal so they form a snug fit against the sides and the sill. This also looks much better.
