Interesting. I had learned a similar design back in the late 1970's early 1980's in school from classmates. I have learned some designs from books, but I guess we had a decent oral tradition, passing down good designs from grade to grade back then. It was probably the combination of available letter-sized sheets of paper (old homework) and some free time (recess and/ study hall). |
