This is another favorite zen-type pattern for me. This makes a 3 1/2" scarf so it's good if you like skinny scarves or if you're making one for smaller kids.
Leftover yarn (I have tons of Bernat Softee)
I hook (makes for a very soft, loose scarf)
Row 1. Sc in second ch from hook and in each ch across, ch 2, turn - 13 sc
Row 2. Hdc in the back loop of the first stitch, *hdc in the front loop of the next stitch, hdc in the back loop of the next stitch, repeat from *, ch 2, turn
Continue row 2 until scarf is desired length.
Last row: sc in each hdc across, finish off
Add fringe if you'd like.
