Mari Sweaters MS 120 Tuxedo Front Jacket
Since Tahki Yarns New Tweed yarn has been discontinued, I would suggest you use Tahki Yarns Coast, available from Tahki Stacy Charles. This yarn knits up with the same gauge on the same needles.
I prefer to join knitted pieces and reinforce edges with crochet,
which produces durable seams and firm edges. This is optional.
