/diy/ - Do It Yourself

I have a garage that we made in the backyard that is open on one side. I cannot block that part with something fixed because I need that open space.

I was using a tarp to block the sun going from that direction but it got caught in a truck and ripped a bit, pic related.

Any option to fix it that does not involve buying another tarp or would you have a better idea to put there? I was thinking about making a folding wooden door but it would take sun most of the day and a bit of side rain, so I don't believe it would last.
