in the middle of the Pink Project

Finally decided I could dive in & transform Toria's pink pieced project into a finished quilt...but so many questions! How big? What pattern in the quilting? Needs to be simple (so Grandma can do it) yet intricate enough that it looks like a finished quilt. Maybe someday she will say "O, I think my Mom picked it up at Target.."

& how in the world am I going to get up from this floor?
