Two continuous curtains for 2 sides and roof, Pure Poly, no longevity against our sunny desert climate.  I'm putting a tan/clear lucite ceiling for outside frame so fabric can pull through. Planning for Sunbrella yardage, maybe match a slip cover to the cushions. 

Also adding a small lightweight chandelier.   

Love the 'Cube'!  It completely covers my neighbors sliding bedroom door, ads a point of interest in the pool area (I will be securing this to keep it from flying away, it is lighter than I thought possible).  

Assembly was easy and didn't take over an hour with 2 experienced hands set to the task. 

Feels Wonderful, looks great, I'm keeping it...
