It depends on the kind of quilting I am doing. I do have a longarm (Innova) on a 12' frame, so it is much easier. If I were doing an all-over pattern I could quilt the quilt in one day. If I am doing custom quilting, it might take up to a week, or even more if it is to be a show quilt. Someone with a computerized system could probably quilt an all-over pattern in half a day. If I were to try to hand quilt it, it would take decades!!! Quilting on my sewing machine is too hard on my shoulders, so I don't do that. I have known of quilts done for show taking 800 hours to make - I sure hope they included the piecing in that number of hours, but quilting quilts for the big shows can be really time consuming!
