Windslits allow air to pass through the banner, preventing damage to the banner. As many or as few windslits as desired can be added, but is recommended that windslits are spaced around 10″ apart from each other and at least 4″ from the edge of the banner. When building your file, we need the windslits to be a 4″w x 2″h half
circle with a 1px stroke on a seperate layer.
