Q:What is the meaning of two flying cranes?
This is an old Russian tradition of painting cranes on laquered boxes like the icon paintings. Many different towns would make these type of boxes. Russian legend claims that the city was a home to icon-painters even before the Mongol invasions. At least since the 17th century, Kholui has been a producer of lacquer boxes, plates, and other painted items that this region of Russia is famous for. After the Bolshevik Revolution, icon painting became unpopular and even dangerous. However, Kholui painters kept painting, at this time in secrecy, giving the area a kind of legitimacy in the cultural/artistic world. The style of icon painting in Kholui is particular to this town, and distinctly different from the more widely-known Palekh style of painting. The icon-painters in Kholui use a large amount of green hues, as opposed to the style of using mostly red colors, as is traditional in Palekh. The Ivanovo Oblast is home to the cities of Putchezh and Kholui. It is found in the center of the Eastern European Plain, and is part of the Central Economic Area of Russia.

Q:War is Kind by Stephen Crane?
War Is Kind Stephen Crane (1899) Do not weep, maiden, for war is kind, Because your lover threw wild hands toward the sky And the affrighted steed ran on alone, Do not weep. War is kind. Hoarse, booming drums of the regiment, Little souls who thirst for fight, These men were born to drill and die. The unexplained glory flies above them. Great is the battle-god, great, and his kingdom-- A field where a thousand corpses lie. Do not weep, babe, for war is kind. Because your father tumbles in the yellow trenches, Raged at his breast, gulped and died, Do not weep. War is kind. Swift blazing flag of the regiment, Eagle with crest of red and gold, These men were born to drill and die. Point for them the virtue of slaughter, Make plain to them the excellence of killing And a field where a thousand corpses lie. Mother whose heart hung humble as a button On the bright splendid shroud of your son, Do not weep. War is kind!

Q:Paper cranes... What do I do?
Okay - so if you can't string them from the ceiling - than what I would do is buy some round vases/globes, from Pier one or some place like that, and fill them with paper cranes, then set the bowls on your shelves/windowsill/desk/table or other flat surface. I've enclosed some examples below. You can also make a mobile by hanging something like a super strength hook with adhesive. 3M makes them (the same folks who created scotch tape). The adhesive does not damage walls and you can stick them to anything. They can bear up to 30 pounds of weight. Put a few on your ceiling or walls and hang your mobiles from them.
