I just finished knitting up this custom order, using the alpaca mix yarn which i usually use in these sweaters, http://www.etsy.com/listing/59792044/brown-alpaca-blend-tweed-cardigan-size but for this M2M I've double knitted the yarn, (knitting two strands together) which basically makes the yarn chunkier, and so the garment becomes chunky
and wow another comfy sweater is born. I think an oatmeal version will be added to my to-do list.
