Featherweight RX, Dave McCallum's business at www.featherweight221.com, has holiday specials going right now. I got his book and DVD combo b/c I just started collecting FWs and want to know how to care for them properly. I bought a bundle of 3 feet for quilters, too. He threw in a guide that costs $11 for free. The book is amazing, haven't watch the DVD yet. I have no connection to this business, just sharing a resource that was shared with me on another board. I have different accessories with each of the 3 FWs I have, and doubt that I'll use most of them. Some do look like robot parts. I would gladly pay for FW classes, even an FW retreat, to learn how to make the most of my treasures.
