Again it comes to preference. Because most of my quilts get high usage as utility or bed quilts I usually will use a stronger thread when quilting. I am not to concerned with the thread for my own piecing either. When making a block or quilt for someone else I try to use a stronger thread . I don't make quilts for others outside family very often. When I do I prefer Glide threads. They can be a bit more costly but IMHO worth the extra.
