2-way 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 yourself and tack the ends to each other then tack the 2 back edges to each other, take it off and sew where you tacked using matching yarn.
Another etsy link that I'm afraid will disappear soon - this is a cute sweater that could so easily be created by making a long scarf and stitching the ends together (you can see in the 2nd picture the ends were stitched together). The sweater is also stitched together in the back where the 2 sections of the scarf come together...I'm making this.
