I love how these scarves turned out, all of them are done with one strand of variegated yarn and another of white or black. I call it my double strand, double crochet almost too easy to call it a pattern pattern, the Too Easy Scarf for short. There are a lot of variations possible, my Thumbs Up scarf uses two strands that are very close in color giving it a tweedy look, this scarf used a strand of bulky in off white and a strand of self striping baby yarn to get an interesting effect.
Too Easy Scarf
Size M or N hook, two skeins matching or contrasting yarn (I'm going to guess about 3-4 oz each)
Row 1: dc in 4th chain from hook, ch 3 counts as dc, dc in each ch (12 stitches)
Row 2: ch3 and turn (ch 3 counts as dc) dc in each dc across
Repeat row 2 until your scarf is as long as you would like
Cut yarn in 12 inch lengths for fringe, attach and trim
Told you it was too easy, perfect for the beginner or if your trying to teach a child to crochet.
