Too late to edit!
After thinking about it, I think to take off the borders and incorporate them on the back with the story, they can frame the story even. I've been adding in stuff that didn't make it to the front of the quilt into the back and rather enjoy it.
Yes, your printer should be able to print on fabric just fine, follow the directions, since it is important if they have an optional step with retayne or other substance, do that too!
You have an established relationship with your quilter and that is important in bartering relationships.
