The tip of the Tri tool is actually not quite 60 degrees. A 60 degree triangle will have all three sides the same length. The one I used has a base and height that are equal, but the sloping sides are a little bit longer.
That's not to say a slightly different angle won't work--I just haven't tried it.
PS: For those who don't like cutting around cardboard templates, I traced around mine with a chalk pencil, and then I cut them (about 4 layers) with my quilting rulers.
PPS: Thanks, Judy!
