did you stitch all the way to the center? If so, pull out the stitching back 1/4" When doing "pointy" blocks...I make sure I stop stitching 1/4" from the ends. On points...measure and mark on the wrong side with a mechanical pencil....draw the line all the way to the edge of the fabric. The marks will cross at the 1/4" intersection...That's where you stop stitching. You will get a whole lot less bulk and can swirl the leftover seam area to flatten it on the back. The bulk will fill in any tiny hole that may result from not getting quite to the intersection.
