I waited until the model was painted and decaled before tying on the parachutes.
The instructions have you permanently tie the parachute to the upper section in Step 22, before finishing. Even though you can disconnected the snap swivel and line, the shock cord and parachute would still be tied to the line loop on the end of the third stage.
That parachute would have gotten in the way with all the masking and painting going on.
The picture at the right shows how the upper section should hang from the 18" parachute. The tower is up, the coupler end would hit the ground first on recovery.
In Step 22, Part C, you cut a 13" long piece of shroud line. That is tied to the snap swivel and shock cord.
In the picture at the left, the distance from the hook to the end of the coupler is 13".
NOTE: To allow for knots, you should make this line a few inches longer. At the recommended 13", it won't be long enough.
The rubber shock cord connecting knot would end up between the coupler and main body tube.
With the line at just 13", you'd end up with a doubled shock cord between the coupler and body tube. It would be hard to slide the coupler into the lower half.
