This quilt will be beautiful. You chose the perfect layout. The brick pattern is great because you don't have to line up any seams. The children will be thrilled to see their blocks in the quilt!!!! I make a quilt with my class every year and it is a great experience for the students. It will turn out fine. If you do another in the future.....you will cut the blocks yourself!!! Enjoy the project. Don't get caught up in the details that no one else will even notice.
