I get a lot of my wool at the local thrift shop. I wait until they have their 5.00 a bucket sale and then I buy 2-3 buckets. I can usually get 10-12 pairs of pants or 15 or so skirts made of 100% wool into them. Then I take them home and run them through the washer with hot water and then dry them in the dryer. After that I start disassembling them. You can get some great yardage this way. My whole family knows that when they are yardsaling they check fiber content on clothing. Word of wisdom though. unless you are getting it dirt cheap blazers are not woth the effort. you only get the back of the jcket for usable fabric as the entire front usually has interfacing fused to it.
