Yarn: Cascade 220 Heathers 100% worsted weight wool, in Pumpkin Spice and Yakima Heather
Needles: 4.5mm / US 7
Gauge: 4.5 stitches x 10 rows per inch
Stitch Pattern: Two-Colour Fabric Stitch
Source: BW3, p. 228.
Comments: This fabric is super dense and - due to all the slipped stitches - very smooth. The back looks a little like and over-stretched moss stitch done in 2-row stripes. I think this would make a really interesting fabric for a waistcoat, especially when done in two very similar tones like these.
