3. Attaching Hood to Base

If the hood size which is to be used is already attached to the base,
proceed to step 4.
First remove the hood which won't be used by gently pulling the elastic
cord at the bottom of the hood out of its channel, working your way all
around the base. When the hood is clear, carefully roll it up and place it
in the carrying case to protect it from damage.
Next, attach the bottom of the hood which will be used to the base. This
is most easily accomplished by first stretching the hood around two
corners of the base, and then pulling the hood into position around the
other corners, keeping the hood seams in alignment with the corners of
the frame. Once this is done, the cord can be pressed into the channel to
keep the hood firmly attached and prevent air leaks. See Figure 3 for
details.
