Here's how I like to trim
the triangle tips or "dog ears" from seam allowances.
It is quicker than trimming each tip individually, and it reduces
the bulk at the intersections.
Before pressing the seam allowance open
or to one side, trim the tips at an angle, beginning at the edge
where the stitching stops. In the detail, the red line shows
the right angle from the seamline - notice that the cut is a

cutter. Be careful not to cut your stitching.

This trimming method is especially helpful
on pieced units that have skinny tips, like the Butterflies
quilt in "Stack-n-Whackier Quilts." In this case, the
cut should be at a very steep angle. Look at the angle of the
fabric on the left side of the seamline. The trimming angle should
be a little sharper.
With a little practice you will be able
to "eyeball" this angle.

easier to match at the next piecing step, and will be less bulky
when multiple seams come together at the skinny points.
