I have the shirley stitcher II. I use it on my queen quilter.
Its pretty user friendly. I think there is about 160 built in
designs. You can get designs from many different sites to download into shirley. Digitech is a real good site. As with
anything you have to play around with it. I really like mine
because I am terrible at free motion quilting so it was worth it to me to buy the Shirley Stitcher.
