I use the backs of mens shirts when I need whites, I buy them second hand, and I only buy ones that are really good quality. I picked up 3 this weekend for a scrappy challenge project, and they were pierre cardin - lovely thick cotton, soft creams and one with a pale cream print. All for $2 australian! The project is a $20.00 - 25.00 quilt top, as that is what we pay per metre down here.
