Yes they do look like a mirror & the TV looks normal when on. Just choose your own frame, some profiles are suitable & others are not. The framer will advise you what will work. I have owned a picture framing shop in the past. Try to find a shop that has one set up as an example.

It looks like the one Charlie Albone did was a plastic screen (Bunnings) adhered to a mirror. Im not certain what type of mirror he used. You might be able to find large acrylic mirrors through plastic suppliers. These would be suitable outdoors.

Hello, how about another mirror - Ezibuy have lovely 70 cm round frameless oak one i have in my house - I have not seen mirror like this before and I love the contemporary look and warmth of the oak. It reflects light which may help in your room and goes with the other circular elements in the clock and the table. I would put it off centre near the lamp and it may even match the wood in the base of the lamp. Have you thought about adding a textured wall paper on that wall.

Before replacing your curtains as this can be quite expensive for such a large window, if they are in good condition, add a band of extra fabric to the bottom in what ever suits you, your existing curtain track can then be moved up to the ceiling for good looking full length curtains without the large round eyelets, could save you a lot of money, I would look at replacing/removing the sheers cheers
