This is easy . . . heat set it with an iron, after you peel off the freezer paper, of course. Or throw it in a dryer on high for about half an hour. I've been printing on fabric for a while now, for embroidery projects, using the prepackaged fabric on paper stuff, which is always white. I haven't tried this technique yet, but I know that heat setting works pretty well with ink jets with the other stuff. Just don't wash the bejeezus out of it. Should be fine for low use stuff.
