The quilt is almost complete....border and then binding.... I/we (my husband and I) are really pleased with it... but I have this final (??) question.



Should I sew the border in black thread all the way up to the outside edge of the sashing border....or just in the black border area??? This is only my second border that I have made and do not know the "rules" for this..... I know, I know....whatever floats my boat, but remember, this "boat" will be going to someone else.

The bottom border comes from the point of the sashing to the point of the quilt....the top border goes across the point side-to-side.... All border lines are either lined up with the half-squares or the center of the sashing. The sashing is sewn stitching in the ditch. The black border has stitching next to the burgandy border....

Any help/suggestions would be appreciated. Again....Should I sew the border in black thread all the way up to the outside edge of the sashing border....or just in the black border area???
