I purchase and use ONLY used flat sheets on the backs of my quilts. They are all donated to charities and I have found them to be serviceable.
I have a few sheets that I have considered cutting to use for quilt blocks. They are soild colors and firmly woven. I do not think there would be a problem for me to quilt them as I use a quilting machine on a frame.
I have also considered using one of these for my leader clothes. I used some heavy muslin when I first got my frame, but the edges take a beating from all the pinning. Now I want to make new leaders and the stronger sheeting appears to be a good choice.
A sheet (or 2) would make a wonderful Whole Cloth quilt. Think how easy that would be. Load sheet, batting and another sheet and start quilting.
I buy my sheets in Thrift stores where I rarely pay more than $3. for the King size flat. Goodwill's prices have gotten too high. But it saves a lot of money on fabrics and time on piecing the back. In my quilting, time and money are both important.
