This cowl looks like it is worked diagonally. However, it is nothing as complicated as that.

This is part of a set that has a pair of gloves, this cowl and a slouchy.

The word “tircha” means diagonal(ly) in Hindi, तिरछा pronounced “thi-r-cha‟ describes this pattern perfectly. (thir ; ir as in mirror).

a) 4-ply fingering yarn (#1), 50 gms / 210 yds ; 4 mm crochet hook ;
