If you are familiar with Value Village, then you already know what I'm going to say. They have large bags of fabric.......all sorts. And, I mean ALL kinds of it, but usually they are large quantities. I freecycle what I don't care for. Usually I'll turn the bag around a lot before I decide if I'm going to buy a BIG trash bag full for $3.50 a bag. I've hit great jackpots. Always wash it anyways and anytime you go in a thrift store you are going to face other's detergents, and scents plus the mold factor. So, if you have health issues, I would not recommend going to any.
I love a bargain.
