What type of thread would you recommend that I use in my Avante. Don't call the quilt police on me, but I throw ALL of my quilts in a warm washer after finishing to give them that old quilty look. Does poly thread have the same look? I am currently using 100% cotton and it has a tendency to break while quilting. I always thought that if you use 100% cotton fabrics that you should use 100% cotton thread.
