Question about bias cut tartan waistcoats.

[Tarheel]

Good point on the darts with tartan Todd. The lower photo, with the dart in the tartan, is well placed and enhancing the entire look. Fine job.

Concave cuts in the side stitching may be a way to go in tapering a vest with a bias pattern and one center dart in the back where two panels meet. I imagine clothes more often than I sew fabric and can see the need to practice with other cloth before I committed to the final vest.
