I did not even know about this! I am now interested in this a lot. Some people say it is 'easier than wallpaper, lasts forever, and peels off clean when you want to change'. I also want to know about the wetness of the starch.

Would go a classic navy and cream , with rich gold accents, like this pic but reverse the wall colour and lounge colour, and with your English lounge choice and decor, it would look refined and classy. The navy would go well with your grey/taupe carpet and the walls, and your window design would lend well to the old Victorian/English style. Just one idea to consider :)

https://www.fabricmill.com/coral-reef-oceanside.html. On their site there is no mention of shipping os, they use UPS. UPS ships to Australia. I suggest emailing or ringing. I have got fabric from Fabric.com. Great service, 7 days to Qld pre-Covic. Be aware that it is usually multiples of US price for us.

I can’t comment on that company but I am very happy with the blockout fabric blinds from Blinds on Line . Some are Roman which have a dressier look and some are roller .
