Elf and Emperor made these Colonial hats with some paper and clear tape. We got the directions from our second-grade social studies unit on how people dressed during Colonial times. The teachers' manual was unclear in that it did not have a cut-out pattern or size specification for the boys' hats. We just guessed, so the hats wound up a little small. These were fun to make and relatively easy to do. As you can see, it's just a triangle in the middle surrounded by three folded boat-shapes. I stapled the corners together so that the hat would stay tri-cornered.
