I needed to build a shleter for my car over winter. I cut some Pine saplings and tied for of them together.
Then I tied four more saplings horizontally to the four uprights to form a frame.
I then draped a parachute over the hole frame-work as a cover.
To drive the car in, I lift up the front edge of the parachute and pull it back down once the car is inside.
As long as I clean the snow off daily it should last the winter.
