I built my house from trees that I felled in winter time (–20°C) with an axe and two-man crosscut saw in my own forest. I did it following the research of old carpenter’s calendar that coniferous trees should be felled in January’s first days when the new moon rises and the deciduous trees should be felled in the winter time during the old moon. In winter time trees are sleeping and the juice and moisture content is very low in them. As time passes timber felled in winter becomes light and strong.
