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.
The example is 5” by 52”
3 oz (85 g)/135 yds of bulky yarn
Size K (6.5 mm) crochet hook
ch = chain
ch sp = chain space
dc = double crochet
v-stitch = dc, ch, dc in same stitch or space
Chain 16. The scarf can be made wider by adding 3 chains for each v-stitch wider.
After first row make all stitches in both loops.
Row 1: Dc in fourth chain. Dc in each chain to end of chain.
Row 2: Ch 3, turn. Dc in second dc, dc in each of dc across to end. Dc in top of turning chain.
Row 3: Ch 3, turn. V-stitch in third dc, (skip 2 dc, v-stitch in next dc) across to last dc and turning chain. Dc in top of turning chain.
Row 4: Ch 3, turn. V-stitch in each v-stitch ch sp across to last dc and turning chain. Dc in top of turning chain.
Row 5: Ch 3, turn. (Dc in the first dc of the v-stitch, dc in the chain space, dc in the other dc of the v-stitch) in each v-stitch across the row to the end. Dc in top of turning chain.
Row 6: Ch 3, turn. Dc in second dc, dc in each of dc across to end. Dc in top of turning chain.
Repeat rows 3-6 until scarf if the length desired. Finish off, secure and weave in end.
