Little Hex Scrap or Charm
When I first started to quilt, I took some classes from Sharon Hultgren. She was an excellent teacher. I bought all her books at the time, as they were learning books and all her rulers, as I was very impressed at what they could do. Instead of templates, you could cut diamonds, Hexes and all sorts of shapes with her rulers and her books all had tutorials on how to use them.
So out came the book and the ruler to cut hexes. I had decided to do 1.5 hexes. You use the ruler to cut the strips for that size. (You can't use a regular ruler for this.) I had some strips left over from my last three quilts so to practice, I pulled these out.
first you place the ruler on the 1.5 mark and cut that angle and then turn and cut the size listed and then turn twice and cut the points off and there you have perfect hexes.
