I am making a cover for a hard fiber glass dinghy out of sunbrella. The boat has 90 degree corners. I installed a templet and found that at all corners i get a pucker. Should i cut a wedge out and sew it together?   
p.s.  The sunbrella hangs over the sides about 2".

The pucker usually results from trying to sew a 90 degree corner -- it can't be done! There will be a radius no matter how careful you are. So you cut a 90 degree angle in the plate and then sew the boxing on with a radius (even though it might be very small) -- the result is the pucker! Try cutting the plate with just a little radius (1/4 inch or so) and see if the pucker doesn't go away.
You may be just sewing a 45 degree angle across each corner at a 2 inch depth to create your 'boxing' (technically it is a 'skirt' here) -- this, too, will create a bit of a pucker but it is usually not enough to worry about (I don't).
