1. Applied a few dozen strips of masking tape to the canopy, marked where the top of canopy frame is, then made marks at 1" and 2" above this as a reference.
2. Filed and sanded the canopy rail notch in the skirt to improve the clearance.
3. Measured, marked, and trimmed off the forward end of the skirt so it clears the fuselage skin.
4. Positioned the canopy skirt on the airplane and taped it in place.
5. Measured down from the reference marks and marked where the top edge of the canopy frame lies. This will be approximately where the top edge of the skirt will be trimmed. I plan to cut slightly above this, and sand it down to the line.
6. Connected the marks with detail tape, trying to achieve a smooth curve.
