The Tall Triangle™ ruler by Darlene Zimmerman will help you cut triangles for divided rectangles that are three times as tall as they are wide.
Divided rectangles are so interesting to work with! You can achieve long skinny points in your piecing without reverting to paper piecing. Tall Triangles is longer and skinnier than the Recs portion of Tri-Recs; it's a 1:3 ration-- three times as tall as it is wide. (EX. 2" wide by 6" tall finished.)
To use, simply cut a strip 1/2" taller than the height of the finished triangle.
