My best wool find was a "Woolrich" brand gathered,calf length skirt in tiny red and black check. I paid $3 for it, felted it and had probably 4-5 yards!! I used some to line a fireplace mantel scarf for Christmas and gave a friend some for Santa's hat on several candle mats! I purchased it at goodwil. I have also cut apart a couple wool coats I no longer wore. I would love to find a white long wool coat at thrift store to felt and dye.
