This yarn is so fine I was having trouble even keeping track to do the ruler wrapping, I think this yarn is closer to maybe 36 EPI. So I've decided to start with a sett of 32, the numbers work out well for that sett, in terms of how many ends I need for the various colors that make up the plaid. I figured that it would be smarter to start with a higher sett calculation, that way after I sample and wet finish the sample, if I want to open up the sett more, my garment will get wider but I wouldn't need to add in extra ends. I was worried that if I start too low for EPI, and found that the twill was too sleazy, then I would need more ends to make the scarf wide enough, and trying to add in extra ends in the midst of this complex plaid would be really difficult. It won't be a problem if I can open the sett and the scarf gets wider, because it should be lightweight.
