Don't forget to wrap the bottom end of your parachute in a heat resistant cloth like Nomex or Kevlar to prevent the ejection charge from burning holes into your parachute.

Re-do the parachute tied to the screw on metal loop 12 inches below the nose cone. Unscrew the loop, remove the cords and loop the parachute in a simple knot around the loop by passing the parachute through the loops of the cord lines. Line the parachute on the ground and arrange it so where all the cords come off the parachute are in the same spot. Accordian fold the parachute like a shirt. It should end with a width of about the diameter of the rocket. Make a z-fold the long way on the parachute, if it looks like it will be too long for the chute protector, make 2 or 3 z-folds. Lay the cord lines along the chute the long ways and then fold the chute over once along the line of the cords. The cords should not go down the entire way, pull them out through the fold about half an inch from the bottom. Now wrap the cord lines around the chute, taking care to not cross the lines with each other. Once that is done, take the chute protector and burrito wrap it around the chute. Make sure the slit that the shock cord goes through is at the spot furthest away from where the fire will be. Fire + Parachute = Very Bad. The parachute+kevlar should act as a plug in the airframe. If the motor ejection does not push the parachute and kevlar out of the airframe, the pressure will push the nose cone out, which will pull the parachute and kevlar out. Both cases are fine.

Shock cord should be 5 body lengths, rather than 3 body lengths.
