So happy about this thread. I am going to be learning to QAYG on my sons quilt, the back of it being black fabric and here's the big part of it...the fabric is a bolt that my Mother had before she passed 30 years ago. I'm not even going to attempt to use it (what a waste). But I can use it for practice quilting and shredding up for dog bed stuffings I guess. Or any suggestions any of you might have. Thank you for starting this thread!
