I live in Louisiana, so we don't have but 6 or so weeks of weather to need wool garments. But people from outside the tropic zone must move here because I can find interesting wools at Goodwill, or, now on the internet. As long as it is not a "worsted" wool, you can felt it by washing the garment in hot water, soap and placing it in a hot dryer. The felted wool does not fray and can be stitched together very easily. You can also knit an item, felt it, and then have a lovely garment/accessory to use. Felted wool is very durable, can be washed, and "breathes" for comfort. Historically, felted wool is what knights of old wore under their metal armor to protect their skin from chaffing/prevent penetration of weapons and provide warmth. Good stuff - please include me if a group gets together.
