I'm new to this forum. I'm not sure if I'm supposed to be asking questions about clothesline here, but I didn't find any forum in StackExchange that was something like 'DIY'. So, I suppose it's okay.

And this is how it looks now:
When I built it, I tightened it as much as I could, but still, it ended up deformed this way.
Do you know what I can do? Should I change the rope maybe? Is it the tightener that I used?
