In the early days I used to hot glue the canopy on. One problem with this methode is the plastic canopy did not like the heat much, so you had to direct the glue, and heat, more onto the correx fuzz. I now use pins, as shown, and drop a tad of hot glue onto the pin on the inside of the fuzz. Cut the pins a little shorter with a side cutter. This works far better and looks scale like.
