I want to make a quilt

I have an extremely short attention span and am constantly looking for something new to do. Right now its quilting. I really want to make one, but a simple one, not the kind where it takes an hour to make a 4" by 4" square. So I decided I'd make Gonk Droid from lego star wars! It's already square and can easily be made out of smaller squares. Here is my first draft of the grid I'll use to make it.

I want it to be huge because what's the point of making a quilt that you can't wrap around yourself a million times. Plus, its just going to be made out of plain squares so it shouldn't take too long. I'm excited! I just have to go get the fabric and figure out what else I need...
