Even "future daughters in law" or even wives, can go..I wouldn't use that as a criteria. If you tell us what the pattern is maybe we can help you choose a quilting method/ and or design. In general, on a sit down machine, I would work very, very hard to roll one side tightly..but I have doubts that a Cali King size could ever fit under a domestic machine...I would roll as tightly as I could to the halfway point and see if it will even fit under your machine arm.
If it doesn't, there is a way that I saw where a lady only used batting down part of her quilt, she did it in thirds, starting with the center..she cut the batting in a wave pattern so there wouldn't be a permanent crease when she joined the outer 2 sides...that reduced the bulk and she was able to a large quilt on a domestic machine that way.
other than that, you may be looking at sending it out or renting a longarm...or handstitching!
