cabled vest/cowl - *Inspiration* this one is knit but you could easily crochet this so pull out your favorite scarf pattern and get to crocheting. You may need to adjust the width of the scarf. Once your scarf is long enough, wrap it around yourse.
Would love this for when I'm working and can't wear gloves. Can't work camera dials with gloves on! Crochet fingerless gloves - no pattern, but looks very easy (double crochet ribbing on wrist, single crochet on hand)
