The only way I've been consistently successful is Brenda Henning's Triangulations! I own the 3.0 version, it's a CD-Rom half-square and quarter-square triangles construction 1/2" to 7.5" in 1/6" increments. She also includes tamed flying geese 1/2 X 1" to 3.75 X 7.5"

For some reason it won't link but if you copy and paste the above addy... will take you to an overview from Connecting Threads. She is showing the 2.0 but they are now selling the 3.0 that includes the Flying Geese.
