From the pattern:

This space-dyed novelty yarn is made up of two worsted-wt strands, a smooth one-ply and a chenille, wound together… . Separate chenille and smooth yarns … .

The pattern calls for the two strands to be knit separately in the pattern stitch. .75 to 1.25 pounds of yarn are needed.

Gauge is given for the smaller needle in pattern stitch. Gauge is also given for the garter stitch portions of the garment, also using smaller needle: 28 sts and 56 rows = 4”.
