CHEZVIES: big quilt in home sewing machine

I am working on this geese quilt. It's going to be huge one, 86" x 90". I've been looking at several tutorial on how to do big quilt in my home sewing machine. Since I don't think so I will be able to tug and move it around, and with my spondylitis problem, it's definitely NO.

I found a pretty butterfly cotton for the back

I have Jera's book Quilt as you Made modern but I am not sure how to do mine. SInce it's going to be 3 parts, Solid panel on both sides and one long geese panel in the middle.

Then I saw this tutorial by Marci Girl Designs which I think it's doable. Well it will involve hand- sewing but that is better that hauling the whole quilt in one go on to the machine.

here some pics from Marci Girl Designs:
