Yarn: West Yorkshire Spinners, The Croft Aran. (100% Shetland Islands Wool, 182yds/166m per 3.53oz/100g skein). Shown in Fetlar 312.
If substituting yarn, a tweed, a solid, or a subtle heather in a heavy worsted weight wool would work best so that the details of the stitch pattern are visible. I suggest a fiber with a little depth, but not much variegation to show the pattern off beautifully. Choose a round wool fiber with memory and minimal drape for a longer lasting, better fitting hat.
