The Ghillie cover is built on a Polyester knotted netting with 1″ x 1″ holes. Synthetic threads are hand tied to the netting. With the netting, you can add local vegetation when out in the field to enhance the camoufalge effect. Throw leaves or sticks on the cover to enhance it’s appearance and to help blend in to your environment. The Ghillie cover is secured to the tent with Velcro ties on the sides of the tent, or use the thread on the cover to tie the sides together. The ghillie cover has a top piece that is 70″ x 70″, and the (4) attached side pieces are 70″ x 60″. There is plenty of material hanging down so it lays on the ground. Secure the bottom of the cover to the ground with tent stakes. The Ghillie cover will fit most blinds that are size 5 1/2 feet by 5 1/2 feet, with an internal height of 6 feet 4 inches.
