The first attempt I made at an A-Wing used a dollar bill, simply because the long rectangle allows you to create a waterbomb base along the back for the fins with plenty of room to spare at the front to double back and use for the cockpit.
For whatever reason I seem to have forgotten what the heck an A-Wing looks like when I designed the first one, intent more on the idea of how to deal with the back fins and the cockpit than actually worrying about the details.
The finished model turned out much nicer, with the characteristic snub nose and straight wings without the rounded nose (like… say, a letter A?).
While they’re not exactly diagrams, I have my notes that include a crease diagram and a few details.
UPDATE (7/16/2017): I’ve refolded it and done step by step diagrams. The fold after you pop up the canopy pyramid is a bit tricky, but you can just massage it into a flat shape. It doesn’t have to be super precise as it’s all hidden below the canopy. If you’d like, you can play with the width of the canopy a little bit (the diagrams below use easy to find reference points, so it may be a little wider than the picture show above). If you’re using a dollar bill, you can use the picture as a reference.
