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.

What sort of leather? Last time we bought a lounge suite the salesperson enthusiastically directed us to their special of the day and we thought we hadn't been looking at leather but it was a surprisingly good price. However as soon as I sat in it I was aware of a faint unpleasant smell. I don't know if smell is a reliable giveaway, or if people can reliably smell it as my husband didn't notice until I mentioned it. So we kept looking and by comparison some of their other sofas had the lovely leather smell you would expect. Only later did we learn there is significant variance in what is sold as leather and I've seen some terrible reviews. https://www.choice.com.au/home-and-living/household/furniture/articles/leather-couches

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 .

I have white fabric chairs and have had luck with Magic stain remover for fabrics, test on a patch under the stool first just to be safe, once dry , treat with Scotchgard to repel stains,this has saved my chairs, both available at Woolies.
