A hole on the floor is not good; then you do not have the protection against damp and insects. Here is how to avoid holes in floors of the Nordic tipi.
When deciding where to place your Nordic tipi, be careful and make sure there are no hard and sharp things on the ground. If so, remove them or find another place for the tent.
Sharp things such as small stones or branches also cause less comfort to bare feet on the floor.
Take off your shoes at the entrance to avoid any debris coming into the floor with the shoes. It is also a way to avoid holes on the floor.
(If you need a space to put your shoes use a porch which protects the entrance from rain as well.)
