Yarn: Unknown grey bulky yarn; I'm guessing its a wool/acrylic blend of some sort.
Needles: 6 mm / US 10
Gauge: 3.25 stitches and 5 rows per inch
Stitch Pattern: Arabic Cross Stitch
Source: CEoS, p. 392
Comments: This is a pretty basic knit/purl pattern, except that in the crosses you knit all stitches through the back loop. It makes them stand out a little more (not that you can tell from this photo!) but otherwise I'm not sure what the point is. Weird...
