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.
Hand knit vest Cross Sweater Capelet Neck warmer in by MaxMelody. This is awesome and doubles as a infinity scarf. Love this idea. This is knit, obviously, but I could create this with crochet, or at least the shape if not the pattern.
