I have done what I can with the T.188 canopy with a pair of curved nail scissors, not a pristine job by any means, but I cut it to the lines. Ish. I glued the canopy on and ended up using super glue on it as the glue and glaze wouldn't hold it in place. It look terrible to be honest and I am disappointed in it, as the canopy doesn't fit right. Bugger.
