Lately I have gotten into doing pieced backings making extra blocks or using orphan blocks from my stash. I really like the look and have not had any problems quilting them on my LA. The result is almost a reversable quilt. Granted I have only done 2 so far. In the past I have used the 44" fab and pieced it with complimentary fabric to get it up to size or simply bought extra to seam it. I have sent out one quilt to be LA (before I got mine) and for that I bought the 108" wide stuff from Thousands of bolts. Feedback from the LA is that she preferred to work with the wide backing. At a recent quilt show they had a special on wide backs so I bought enough for 2 quilts. One was a green batik and the other was a brown with a little pattern to it.
