1. Collect colourful leaves
This is the time the leaves are turning all the most amazing shades of yellows, oranges, and reds. Go for a walk and see what colours you can find. You can either revel in the joy of finding one of each different shade, arranging them into some form of land art. Or you can take them home, look up the bazillion fall leaves DIY tutorials online, and make something gorgeous that will last.
