Cut 12 lengths of rope at 80 inches each. Use your measuring tape and scissors to do this.
Fold one piece of rope evenly down the middle. Measure 8 inches, 15.5 inches, 23 inches and 30.5 inches from the center of the rope. Mark each measurement with the marker.
Using the overhand knot method, tie two lengths of rope at the 8 inches mark. Repeat this method at the 8 inches mark until the ropes are closed into a loop. Repeat the process for all of the other marks on the rope. This makes the net go from wide to narrow as a basketball net should.
Burn the tips of the rope. This is done to avoid fraying.
