Frequently Asked Questions
How do I decide between triangle and square shapes for an irregular yard?
Triangles are the best default for odd yards because three attachment points are easier to find and tension than four in irregular layouts. Choose squares or rectangles only if you have four solid anchors roughly aligned; otherwise a triangle or custom asymmetrical sail will give better real-world coverage.
How much extra fabric should I allow when measuring for a custom sail?
Leave about 0.5–1 foot (15–30 cm) extra per side to allow room for hardware, knots, and proper tension. For larger sails add slightly more to compensate for stretch and to avoid pulling the fabric into nearby obstacles.
Is breathable HDPE a good choice if my yard gets heavy rain?
Breathable HDPE excels at UV protection and airflow but is not fully waterproof — it allows water to pass through so you won’t get pooling but you also won’t get a dry area underneath during steady rain. For true waterproofing choose coated polyester or canvas but expect heavier fabric and stronger anchor requirements.
