I just found a set of Tulip fabric pens (packaged just like water color pens) at Walmart yesterday, and plan to use them today to produce a doodle on white pre-washed fabric, then let it ride though a few loads while I do laundry tomorrow to see if they fade. I will make an extra, small unwashed sample to compare the washed colors to. I will post my results.
(I once used a sharpie on a comforter/bed spread I bought that had pale red roses, to make them bright red to match my room. Took me weeks of coloring but when I was done, I loved it! Remember that sharpies run/bleed badly on fabric, but this one instance it was not a problem.)
