Yes the backing is included. I figured 5 and half yards would be enough since the fabric is 45" wide.
I'll be binding it, and probably tieing it off. I'll see if thats okay with her first though. If I did quilt it, I'd have to find some one with a long arm, who doesn't charge a lot, which is hard now a days.
She wants it by next month... I know that it will probably take me a week or two to get it done... Unless I have to find someone to bind it.
