The muslin that I have is thin with a loose weave and it is not good for any part of a quilt. However, it is great for quilt frame leaders and for sealing the back of a quilt top (keeping loose threads from getting everywhere) when I need to wash it with color catchers. It's handy stuff to have around, good for quite a lot of things. I bought a whole bolt from Joann's, at half price, thinking to use it for machine embroidery practice, but I have not.
