Stuff the bottom section loosely. Take measurements and make sure that
you are on target and haven't made it too small or too large. This
is your last opportunity to make adjustments without major surgery!
While stuffing, you need to keep the tube situated so that the bottom line
you drew stays parallel to the floor and the width and depth mirrors yours.
Finishing the bottom:
Cut an oval of your hip area out of 3 layers of cardboard or the foam board
to secure the bottom. Cut the center out for the 2" PVC to slide
thruough.
Place the oval on the tube and slide it up to the bottom of the form.
Position the cardboard oval so that it rests right on your marked hipline.
