There will be green baize enough for Martha's room & ours;-not to cover them but to lie over the part where it is most wanted, under the Dressing Table. Letter 51

Ja was using green baize sensibly- under teh dressing table,wher a lot of waer would take placeand where a lot of hair and powder migth harm teh surface of a carpet.

However, one of her characters makes and almost obscene habit of using green baize to excess.......I often wonder if the whole of the White House the home of Mrs Norris in Mansfield Park was covered with this stuff......

Mrs. Norris contrived to remove one article from his sight that might have distressed him. The curtain, over which she had presided with such talent and such success, went off with her to her cottage, where she happened to be particularly in want of green baize. Chapter 20

Here are a couple of pictrues which illustrate just how green baize was used : as a drugget- to protect expensive carpets from uneven wear and tear and also protect them from sunlight.:

Bearing in mind only Mrs Norris and her housekeeper live at the White House it seems considerably like over kill to me ;-)
