Abstract: A tether apparatus is disclosed for coupling a sheet material to an object. The tether comprises a clip having a first jaw member and a second jaw member for grasping the sheet material. A strap extends between a first end and a second end. The first end of the strap is secured to the clip. The second end of the strap defines a closed loop. A continuous cord extends through the closed loop of the strap for encircling the object and enabling the clip to be inserted within the continuous cord for securing the continuous cord to the object. A keeper slidably engages the continuous cord for adjusting the length of the continuous cord by the position of the keeper on the continuous cord.
