Pattern uses 2 8 oz skeins Blue Heron metallic yarn for all sizes. There will be sufficient yarn left in sizes small (32”) and med (36”) to make a decent sized scarf. Sizes L (40”) and XL (44”) will have leftovers as well. Arm length (6-6 1/2”can thus be adjusted if desired. Cardigan is slightly fitted and can be worn with some negative ease.
