What is a detailed description of the wallpaper in "The Yellow Wallpaper"?

The narrator first describes the wallpaper as irritating and provoking, "and when you follow the lame uncertain curves for a little distance they suddenly commit suicide -- plunge off at outrageous angles, destroy themselves in unheard of contradictions."  In other words, then, the loops and swirls of the wallpaper, probably slightly textured as wallpaper often was during the Victorian era (which would also explain the yellow dust that seems to come off on the narrator's clothes while she "creeps" around the room) do not seem to possess any sort of discernible design; they simply swirl up and drop down crazily, and it really bothers the narrator for quite a while. 

Further, the narrator describes the color as "repellent" and "revolting"; it seems "unclean" as though it is associated with decay.  She goes on to call it a "lurid orange" in some places and a "sickly sulfur" yellow in others.  So, she is repelled and revolted by the color because it seems dirty, disgusting, and diseased.  Moreover, orange and yellow are colors that we seem to associate with chemicals and even toxicity. 

As the narrator continues to spend time with the paper, she begins to attribute a life to it, as though it can think and feel.  She says that the "paper looks to [her] as if it knew what a vicious influence it had!"  She notices one place "where the pattern lolls like a broken neck and two bulbous eyes stare at you upside down."  Her descriptions of the paper, especially when she describes it as "committing suicide" or lolling "like a broken neck" really affect the mood of the story and foreshadow the increasing mental instability of the narrator.  She is very unwell, and our first clues to this come during her descriptions of the wallpaper.
