I have had really good luck with Adger Water Erasable pens, were recommended by Kelly Cline in a class I took. She recommended putting baking soda in water to spritz on marks. She uses it on everything-satin, doilies, lace and fabric. I have also found that Crayola Washable Markers work well. I always try on fabric before I start marking to make sure it will come out and only the red and orange colors have been a little difficult to remove.
