I have used a product called transdoodle that works very well but rubs off easily. I would be hesitant to use the Saral stuff for fear it would not come off but you can easily test it on a scrap peice of fabric. If I remember correctly the white was kind of chalk like. I have had good luck with the Transdoodle. You can get it lots of different places, just google it. I bought the larger size pieces and like the saral you can reuse it many times before it doesn't transfer anymore.
