Kobenhavn is a reversible triangular shawlette or shawl. The construction of this shawl is non-traditional. The shawl is CO at one end of the garter stitch triangle, increased to the desired size then decreased forming the triangular basis. Stitches are then picked up along the sides of the triangle, and a feather & fan chart is knitted top down. The shawl finishes with a knitted on edging.
