When you are piecing, and you add the small triangles to the big ones? Make sure that the little ends that hang over are even on both sides.
They make a tool that you can use to cut those little ears off. Then you can just line them up evenly and consistently every time.
It is called a triangle trimmer, I have the ones made by Fons and Porter.
Or, you can paper piece them like I usually do LOL
