I reccommend using a yarn that is soft to wear against the skin of the face. You can use Light Worsted to worsted

Errata in the two needle version - that has now been corrected on the downloadable pattern. The two needle version should read as follows:
Cast on 120 stitches
Work 3 rows garter stitch

Row 1 of pattern: k2tog twice (“yo, k1” 4 times, k2tog 4 times)repeat until last 8 sts, “yo, k1” 4 times, k2tog twice
Row 2: Purl
Row 3: Knit
Row 4: Purl

Repeat the pattern 12 more times (or until length desired)
Work row 1 of the pattern
Work 3 rows garter Stitch
Cast off
Make up
You should have a straight edge at the top of the Cowl & a scalloped edge at the bottom. Weave in ends & sew up side seams. Block if desired.
