So after getting canceled due to weather earlier, we finally got to try projecting the sun onto paper for astronomy class. When searching “Projection on paper”, you get the occasional astronomy reference. This is because one way of viewing the sun safely is to project its image onto paper. This can be done a number of ways, including simply poking a pin hole into a note card and then holding it in the suns path. You can also use a telescope that is greatly filtered to view the sun, as well as thick welders glass.
