The machines I have found at estate sales were just lucky finds. The thrill is in the hunt! A couple of months ago, a brother and sister advertised an estate sale of their mom's patterns, notions and fabrics. What I found was jaw-dropping! There were well over a thousand patterns neatly sorted by styles (dresses, vests, coats, totes, costumes, etc). I left with an overflowing extra-large laundry basket stuffed with Moda and Thimbleberry fabrics for $20. Final count was over 60 yards!! I found new metallic threads, serger cones, needles, etc., etc. For me, that day was better than Christmas!
