You can make this simple little scarf in an hour with one skein of bulky yarn. Stripes of V-stitch and double crochet make this simple scarf far from plain.

The example is made with Lion Brand Jiffy, a bulky yarn. The scarf can be made with lighter weight yarns and smaller crochet hooks. You can add beginning chains in multiples of 3 to make the scarf the width you like.
