My avatar quilt is a generous king size done on my Janome that has a 9 in throat. Yes it is hard to do, you have to have lots of patience and I also scrunch it up as opposed to rolling it. Between shoulder surgery and MS, some days I don't have much strength in my arms, but, it is very doable on our domestic machines. I haven't sent one out to the Longarm lady in probably 4-5 years. There's something about starting and finishing it myself.
