It is kind of funny. Most say don't use it for quilting. I made a quilt for someone who picked out her own fabric. I learned that lesson the hard way. Anyway, one of the fabrics, I have no idea what the content was. I ended up having to serge every seam that that I had sewn to keep it from falling apart. Every time you looked at it this fabric it had raveled a little more. On this quilt it was a life saver, but normally I would not have had to to do this. I always have to learn my lessons the hard way.
