This shade sail is VERY large and sturdy!  The grommets are sewn in very securely--likely it will be very tough for them to tear through even in strong winds.  Thats what we are hoping for because we live with some strong east winds.  The seams are reinforced along the entire edge about every 12 inches.  The fabric feels like nylon rope and has some breath ability who should help when windy.  However, I dont  have pictures yet because no hardware came to install the sail and we arent sure what to get! No instructions either. If you are a Gee-whiz with these kinds of things I recommend this product.  If you are more like me--maybe just ensure that the sail you buy comes with hardware and instructions.
