Only on one chair, I am a tad obsessed.
All the furniture in my lounge room is White..
I have a lovely big lounge chair, and it is in a white fabric....I like to just place a big polished cotton white throw on it....so I don't have to wash the 'slips on the chair' much.
I have 3 throws, each is changed once a week.
Other from that I don't use them.
Mine stay in place because they are big enough...don't give me any grief really.
(my pic is my chair I have)....Love it, so comfortable. :)
I've the comfy chair which I bought to 'nurse' my baby, & that now has a colour-coordinated large cotton sheet over it, to match Lounge Furniture upholstery.
The chair is beige, & because it's been covered since it was bought, no discolouration has occurred. I just wash the sheet when I feel like it, hang it on the 'Hills Hoist', & when dry, is draped over chair again.
As its dried in the sun, & wind, it's wrinkle-free, looks outstanding, & smells beautiful!
I enjoy relaxing on it, either reading the newspapers', or listening to my Quad Stereo System!
