How to make a custom built radiator cover really cheap (or for free if you already have offcuts lying around 😉) Is this too much information, too quick? If it is tell me and I'll do a slightly longer video on it for you. I'm so happy with how it turned out and it didn't even take long to build. I used 4x1's for the side pieces, (because I had them) and that was as far as I needed to come out for this radiator but some are deeper so be sure to measure how far out from the wall you need to come.
