Get a very fine sandpaper and put your pressed and starched fabric on that before you write with a very sharp, water proof marker. You may have to practice some- you CAN'T pause and decide what else you're going to write, because even a slight pause will make the marker bleed. Keep going SMOOTHLY . If you write it out first, you can get the spacing right and the way the words flow, so you'll have more success with the real label.
