Here's the belt pattern: Keep in mind the Noro Daria is very stretchy!
I used size 7 needles, a fabric glue to secure the ends, because it didn't seem like just weaving them in was going to stay, and regular sewing thread to secure belt around the buckle.
Cast on 6 stitches. Knit a row. Purl a row. Repeat until long enough to go around, plus 2-3" to secure around buckle. Decrease one stitch at each end for two rows. Bind off last two stitches. Put the first end through the buckle and sew to secure.
