The cotton I use the most is Saucy, from JCA, a trusted name for as long as I can remember! The New England wool is one that I've been using for a while and I love it! It wears well, washes nice, and best of all, I can buy it locally. And my favorite, Lopi, a Icelandic wool, is the warmest and will last you many years, titleing it a Heirloom! Click to enlarge.
