Kinda hard to explain! When you put your pin through the two seams, you'll see why it's so hard to sew them correctly because the seams don't line up.
This is what I do. It really saved my bacon while working on a Buggy Barn sailboat quilt for my son. Lots of 1/4 square triangles in the sashing of each block that had to meet the points of the triangles around the next block! If I hadn't stuck a pin through where the point should match, it would have been a mess. But don't be so hard on your self. You have done a fabulous job! I love that quilt. Very pleasing color choices, too. And once it is quilted and washed, the distance will close and you really won't notice it.
