"This cocoon cardigan is gorgeous and quick to make up! Textured and beautiful, we love this design! Fall colors make this a MUST HAVE for the fall wardrobe! Calls for #5 weight yarn and 6.5mm hook. Written for adult s/m, l/xl, 2x/3x and 4x/5x Your main panel will work out as approximately: s/m - 38'' x 29'' l/xl - 43'' x 31'' 2x / 3x - 48'' x 33'' 4x /5x - 53'' x 35'' I used approximately 1100 yards #5 weight yarn for the size large in Hayfield Spirit Chunky. You will need approximately 900 - 1700 yards depending on the size you want to make."
