Decorating Of Christmas Trees

My son who 6 years old now has gifted me several brilliant ideas how to decorate Christmas tree at our home. Before when I was decorating Christmas tree for myself and used standard decorations from any local supermarket. That was nice - but not special. When he was 3, he was still playing with soft toys and had plenty of them. So, we put those small and bigger toys on Christmas tree and that was actually excellent. Afterwards, at the age of 4 - he was extremely interested in cars and Dakar race that starts around New Year. This is why we put many of his small cars on our Christmas Tree. At age of 5 - he learned letters and figures and we decorated Christmas Tree with them. This year, at the age of 6 - he's big fan of Lego toys and made decorations mainly himself - not exactly as it was written in manuals by Lego. This is old tradition, how decoration of Christmas Trees was invented - not to buy toys but to make them during long winter evenings. Just in modern style :)
