I agree with this.  The Sunbrella seems VERY stiff.  Lucky for me it fit the
way it was sewn.  1/2" shorter and it would not have fit.  However, this is the
sign of a good design...fits taut and with no bagginess.

Also, it was indeed tough to close the poptop the first time.  I found that
gathering the material such that it didn't poke through was a bit tougher
(especially at 2AM when I couldn't see anything :-).  Also, the canvas I bought
did not have an elastic strap in the back to automatically gather the material
in the back.  This is something I'll have to check for or sew in my own elastic
strap.

I also installed a new poptop seal from the Bus Depot (good stuff, BTW...just
presses on), so until that settles in place, it may have offered some
resistance to the poptop closing as well.
