Ages ago, Practical Crocheter posted a pattern here for an easy scarf pattern, worked corner-to-corner, using one 100-gram ball of worsted weight yarn and a size L (8mm) hook. Yes, the size L hook does work with worsted in this pattern, and the diagonal orientation of the stitch creates an almost woven looking fabric. Working on the diagonal is also a fun way of managing pooling with variegated yarns.
I've turned that pattern into a free printable, so enjoy!
