I loved paper airplanes in elemenary school. I ordered this book from some school book club thing. It comes with many well decorated tear out paper airplane templates. Some of the designs are quite good. Since I didn’t like the temporality of the tear out pages, I learned how to make the planes by reading the crease marks and imitating the designs. My copy still had all the original pages. If you have access to a copy machine, you can just make photocopies and preserve the originals.
