They have fabric for inkjet printers you print on it just like you would paper! I love it for pictures too!

The best way I have found is to take a piece of fabric to one of the places that embroider on t-shirts etc. They had me bring a piece larger that what I planned to use. They marked the size block I wanted and embroidered and did a beautiful job. The price was less than I expected. I find that when I print on fabric it fades more than I would like with washing.

I have used Micron pigma pens & a small (around 1 inch) alphabet stencils to write on fabric. They will hold up with washing. Just iron freezer paper on the back of your fabric to make it easier to write on. The pens come in several colors & are a very great product. You could probably find the pens in her school colors as there are many colors.
