If you can, just shove that puppy into your machine! I don't know how big a Viking Rose is, but I FMQ'd a 120" square quilt on my Janome 6600, that has a 9-inch throat. Worked fine and that was my first ever FMQ quilt.
I don't roll up my quilt, I just cram it in there and flatten out the immediate area I'll be working on. The rest of the quilt puddles around the machine. Just flatten your work area as you go and make sure you don't have a corner of the quilt sneaking in underneath. Support behind and to the side of the machine helps greatly.
