Welcome to the forums.

When was the last time it was up? It could be a temperature thing if you put it out in the sun and let the material warm up you may be able to see it stretch. However, you should inspect the material to prevent any ripping or anything else.

 

Np, let me know if you have any success.

 

how did it turn out?
