Depending on what you are working with here's a nice one if it's wood.

Take the canopy, window or similar and make it oversize (around 4 to 5 mm) to the place it is supposed to be (the frame of the window) Take the oversize window and hold it against the spot where it is supposed to be. Take a pencil and draw a line arond the window. Take the window away and take out the excessive material in the frame for the thinness of the window plastic.

Take the plastic window and drill 1mm holes in it 5 or 6 will do on a flat surface (going around curved will take more little holes)

Take the frame and clean it up. Now make 5 min epoxy glue and put a thin line in the "cutout" in the frame. Take the window with the holes and put in place gently pushing it in the glue. Now take some puns and stick them thru the holes into the wood (all the way). Leave them there for the next 30 min and you can take them out. Carefully sand the frame down to the plastic and you are all down. Flush windows in a wooden frame and NO problems.
