I have large spools of thread for my serger and free with sewing machines. I am beginning to use his for piecing, hand work and quilting. It started because I was trying to save money . I tested its strength and it was stronger than the cotton I was using. Originally there were no quilt police as quilts were made using any fabric any thread and batting. In these times we must go back to our frugal beginnings. The quilts will look the same and last. But most importantly they will be loved.
