I am currently quilting my 2nd ever to make quilt on my Viking Topaz 20. The quilt is approximately 93" x 97". Guaranteed it is a pain, but so far I am managing with only a few mess ups. It isn't going to the Quilting Show, so I am not stressing about a few mistakes. None of it is perfect, but my daughter can't wait to get it, and that makes me very happy. :-)
I hope this helps with your decision.
BTW, I am stitching in the ditch, nothing fancy.
