River Delta (it looks like one!) is a fast and easy-to-knit scarf that begins with a wide bottom in a rib pattern and decreases to become a long, narrow scarf. Reversible so either side can be worn as the right side. Place the fan part in the front, wrap the narrow end around your neck, and tuck it under the front. The narrow part of the scarf can be knit as long as you like. Knit it in any weight of yarn by changing the needle size to suit the yarn.
