Over the winter holidays behind many impressions. The most striking of them is the New year. This is the holiday, which is always looking forward to and which begin to prepare in advance.

Dad hangs on the branches of the garland, my brother and I decorate the forest beauty Christmas toys, and my mother – tinsel and "rain". On the window stick snowflakes and figurines of fairy tale characters that are cut out of paper. It turns out very nicely.
