If you would like to make some retro flights the best material to use is a square Post-It-Note. Post-It-Notes are available in a large range of colours and they are the idea size to make a dart flight. The only change we can make to the above is to trim the side so that the flight looks like a conventional dart flight. If you have an old dart flight, use this as a template.
Paper flights became commercially available in the 1930’s, these flights came pre-gummed similar to an envelope adhesive. You still had to fold them the same way as McKenney’s patent but the flight design was different in shape.
