Design Disgust?

So I am working on the quilt I mentioned in the last post. As you may be able to tell it is made up of different shades of purple and grey. Well, I don't know if anyone has noticed but there is like ZERO grey fabric floating around out there. I only found two shades of grey at my local Joanns, both different weights and had to order a third (which seems to be a silly waste of money). I went looking for more yardage of the darker grey today and it was nowhere to be found. UGH. I also just want grey striped fabric for the binding!! Why can't anyone carry grey striped fabric!?! I am seriously doubting this project, despite the top pretty much being finished.
