This two-sided structure needs one long, sturdy pole (thick branch), at around 9 to 12 feet long. Prop it up in the fork of a tree, or between two forked propped sticks. Cover the sides of the pole with smaller sticks and branches to create the “ribs”. Place them close together to avoid the shelter collapsing. If it is a Cabin you can use oak wood, and plaster to keep it warmer.
Hope this helps!
