that is all I use for sewing anything. the big cones last sew much longer than the small spools and are so much cheaper. Especially since DH bought a whole box full at an auction sale and I bought another box on the same sale. I will never run out of thread. Have just about every color under the rainbow and my machines have no problems using it. I always double sew my seams when I quilt sew it will never come apart unless someone takes it apart.
