I stacked the split wood in a large round circle rather than in rows. That way the stack stays up without any end supports. Once the stack is high enough I put loose pieces in the middle. It is an old world method of sacking wood and it works quite well.
The wood is mostly poplar and spruce. I will burn that in the fire ring outside. The oak, ash, and maple are stacked near the house and will be used for heating in the house.
