I am not as quick to buy a new ruler as I once was but I love there is so much available. I will never have a long arm because I would feel like I would have to make it pay for itself and making quilts is my hobby and not a job. I love to learn new techniques, appliqué, hand quilt, etc. I have found there is no standard as far as accurate measurements on rulers and if you use several, your corners will likely not meet.
