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.
Cable poncho - this is a retail item ~ two rectangles, stitch to desired arm opening ~ stitch to form shoulders leaving a collar opening. pick up stitches for generous rolled collar . co slightly loosely! Hmm think this is doable!
