Estate and garage sales are great especially if plus size clothes. Don't forget to look at kids clothes though. There's a lot of material in some of those little girl skirts. I made out like a fat rat at a sale once when it was plus size and the woman wore patio/moo moo dresses out of cotton. I always wash in vinegar, Arm and Hammer soap flakes and my regular detergent. I use pre wash sprays to help rid. I have also soaked perfumed fabric in a bucket of ammonia or vinegar to help cut the perfumes oil. May seem like a lot of work but when you go home with as much as 10-15 yards of material for $5.00, what else can you say. Saw woman the other day walk out of SA with 3 bags of flannel, cotton shirts, skirts and wool jackets and skirts with the biggest grin on her face. I asked her if she was a quilter and she said yes. She spent about $15.00 and had the biggest grin on her face.
