I quilted large quilts on my DSM before I got my longarm. I used the methods in Marti Michell's book, Machine Quilting in Sections, for all but one of them. That one was huge and couldn't be divided up into sections, so I basted it with water soluble thread on a John Flynn frame and then quilted the whole thing in my Bernina 440QE. (That was enough to persuade me to get a longarm, LOL)
