Take heart! I also started Q for Kids and mis-read the directions, and had used all of the border fabric in the process. I called and they said not to worry about it; just make it and it will be okay.
They said the only 2 problems they have are people who get a kit and don't return it, and using too heavy a batting.
So, I am finishing mine with the wrong blocks sprinkled in the quilt, and it is okay. I am using double flannel sheet, which isn't as heavy as the batting, but I didn't have the right size, and our Wal-Mart was low on everything in batting, and didn't have the weight they mentioned.
So, don't worry about it, as it will be fine!
