I love estate sales! Sometimes you'll find excellent scissors, fabric and they're always an excellent source for thread. You can't beat a bag full of thread for $5 vs $3-$10 a spool new. Two really stand out in my mind. The first was the estate of a quilter. The entire second floor was full of quilting stuff -- as was the first floor. Members of her guild were on hand to help and it truly looked like a quilt shop! I got my hard wood cutting table there. The second one was a tag sale at the home of a fabric designer. An INSANE amount of fabric -- and cheap, cheap, cheap.
As for my will -- I was actually just preparing an update and decided to give my machines and fabric to the local guild. My son actually asked me if I'd mind if he kept them! I was happy to do that.
