Autumn
Invent something for autumn
Fall into autumn!
Today is the autumn equinox which marks the start of the fall season! We want to see some autumnal inventions that will make us want to curl up with a hot drink and a book as we watch the leaves fall outside. You could use those leaves as a resource for your creation, or acorns, or even pumpkins!
