Sarah one option to consider is getting all of the numbers screen printed on to a small piece of bumper fabric and then sewing that "badge" onto your full sized pieces of fabric.

You can do the same trick with paint using a stencil that allows you to swap out numbers for all of the different teams. I have heard of some teams who used spray paint in the past so that might be feasible way to get a lot of numbers painted without having to hand paint every number.
