How to attach a shade sail to a pergola?
You can determine the size of your pergola sail from the size of the existing frame. Remove 5 to 10cm lengthwise and widthwise so that your fabric can be attached to the frame using the black cord provided. The pergola fabric will have straight edges with eyelets every 20-30cm to create a zig zag between the sail and the frame. Provide pergola hooks on your wooden structure if necessary.
