As busy as the pattern seems at first glance, it really does work in my dining room. Somehow, the pattern appears muted from a distance. 
To those who care about such things: the pattern placement on each curtain is very nearly the same. It looks as though there is only about an inch of variance among the 4 panels I purchased. 
They are heavy curtains and I have high hopes that they'll combat our somewhat drafty windows this winter. 
There are about 3 shades of green, ranging from sage to almost hunter green, with the lighter shade(s) being most prominent.
