What you need:
4 Tent Pegs
1 Hiking pole
A type of guyline[I used 10ft of paracord]
Step 1: The model
I marked the paper with a Sharpie where the grommets are.
Since I didn't want to add grommets I cut it on the dot in the boxes that are on the picture and made a triangle.
Then I folded the paper in half.
This is the model I went off of.
