I've been to enough estate sales around here to see all the outdated fabrics and notions that go unsold and think about the wasted money. Most of that stuff ends up in a landfill after being a hassle for the survivors to deal with.
I don't care where you live in the US or Canada, if you post online "Free fabrics and notions" you will have people coming out of the woodwork to get them. No need for the landfill. Yikes.
