More carefuly cutting! Put in another long day of carefull trimming, sanding, and shaping edges to remove any stress points that might lead to future cracks. Much time was dedicated to placing and trimming the canopy so that it would lay naturally along the lines of the canopy frame. I'll be sooooo glad when this thing is done. It takes two of us to securely move the canopy around as it has no support at this point.
