Why Do a Y Seam?

This looks a bit strange, but the triangles will all be the same size (or fairly close to the same) once this block is sewn together with the others. Right now a few of the triangles look funny, don't they? Of course, the final seams will take care of the problem.

This is "H-10, Ben's Bowtie", an intermediate-level block that I chose to paper piece. The software printed out the sections so that several Y seams would be necessary, but I redrew the sections to eliminate all of them. The Y seams only make things more difficult, in my opinion.
