I am thinking of building a steel pergola and using steel cable (like they use on boats and as a guard on handrails etc ) as the sliders to hang roof blinds held on with rings.
The idea being to pull closed if shade is needed or pull back if warmth is needed !
Sunbed type fabric may be too flimsy so I want to talk to a boaty sailmaker type guy (may be too expensive though !)
Does anybody have any contacts in these type of ship chandler places ?
