The main reason you probably haven't heard from "M" is due to the retreat they have going on right now.....MSQC is celebrating their 7th Birthday, so I am assuming that's why you haven't been contacted. Not sure, but I doubt ( I have never asked ) that MSQC would fussy cut items....???
I would try to call them the first thing Monday morning if I were you.....don't forget the time is different in Missouri than in Maine as well.
Have you called to see if any fabric stores in your area might have the fabric you need ?

Here's some Ford Fabrics ( I actually didn't know MSQC sold this type of fabric ! )

I would call around to fabric stores in your area today to see what you can find locally.
