This is the medium weight fabric that works for just about every kind of garb. And the color looks right for Calontir. Remember the discount code "ilovelinen" for another small percent off, too.
And no, they aren't paying me to mention this. Wait, do you think they might?
It's probably too late for new Pennsic garb, but order it now & it might arrive before you leave, so you can have it to look forward to when you get home.
