I love late summer and autumn in Switzerland. I love chestnuts. There are all kinds of chestnuts. The ones we mostly found are not eatable but you can make nice crafts with them or use them to play cooking.
With knifes, toothpicks and awl we made small figures.
This last one is a different kind of chestnut- very prickly on the outside and the seeds inside are small, but they look nice.
Of course we also had to taste hot chestnuts ("heissi Marroni" in Swissgerman). Something you can buy on the street in autumn and winter. Tastes good and keeps your hands warm for a while...
