I am getting ready to use a sheet as backing for a quilt. It is cotton/poly but has been washed Lord knows how many times in industrial machines. No pills and it has the perfect 'hand' and color. (I am recycling all the linens DMIL had in her assisted living apartment. She lived there 7 years and had single and full sheets - they all have been washed to a fair-the-well so I see them as perfect candidates for yardage.)
