You can stake down one side of the Tunnel
Dome and pull it together manually, or you
can use electric fencing wire to pull the two
sides together.
Each hub on the ground will have two holes
facing the ground.
Once the Tunnel Dome is the correct width,
take a short piece of rebar or other metal
stake, place it inside one of these holes, and
pound the stake into the ground.
Staking the sides of the Tunnel Dome will
bring the design to full strength.
