Start with a table top setup in the middle with both middle layer bases pressed together.  Now have 2 elevators on either side of the table top extend up and hitch to the lower backs of the table top. 

NOTE: Make sure the elevators are placed slightly back and NOT out to the side.  This will make it easier for the flier to stand up.

When comfortable, have the elevators pop and guide their fliers to the table top.  At the same time, the top fliers will need to stand straight up on the table top, stay tight, wrap around the other fliers waist, and bring their feet together. When stable have both girls pull opposite stretches for the finish.
