This is a collar to wear over a plain sweater or inside the collar of a coat. The pattern was based on a collar created by Edda Lilja Gudmondsdottir with her permission, but is created with a different design and construction to use Drops Cloud, a super bulky yarn. Two balls will be required, but you will only use part of the second ball. If you use an alternative yarn with less halo, you may need to adjust your hook size and starting chain to get the same final size of collar.
