Illegible embroidery I'd like some help figuring out what this embroidery says, if it says anything at all. It's allegedly from China, but I don't have access to the physical object, just a few photos. 

Random characters I can sort of pick out:


Upper right: 豕(?)常
Upper left (and again somewhere in the middle): 中
Near the top of both left and middle: 王
Several on the right (not in a row): 窗, 月, and 有 
Signature: 豈 (and something else)


The level of illegibility is such that I'm not entirely sure I believe that all of these are characters, but someone (somewhere) went to the trouble of sewing it.
First vline is a poem :寻常一样窗前月，才有梅花便不同
