Another great source is estate sales and ebay/craigslist. Often a person has lost an elderly quilter and is trying to dispose of their 'workroom'. They will bundle huge stacks of fabric, boxes of precuts, bundles of tools/notions and other equipment. They are often at a great price and usually the person is so happy to find someone who will put he items to good use that they drop the price or throw in extra stuff. I have purchase many boxes that are so full of surprise goodies. Think about your workroom. How many precuts have you impulse bought and never done anything with? or that kit that was a great deal? specialty rulers? you get the idea. And, I think the person who passed would be pleased to know a quilter is getting use of their stuff instead of it being discarded.
