CoBaSi is a Cotton, Bamboo, Silk (get it? Co! Ba! Si!) blend, with a bit of elastic nylon thrown in to make the most wonderful warm-weather garments and socks. With 26 vibrant colors, we see stripes, and lace patterning, and cables in our future. At $7.50 per 220-yard (50 grams) skein, it’s also a really well-priced option. It will make fabulous baby garments, light-weight adult sweaters, and, of course, socks.
