My chocoholic sister!!! If you notice the chocolate right away, put it under cold running water and gently scratch with your fingernail. I find this works well on small spots on my white-ish fabric. If this doesn't work, try one of the suggestions already made. It's important to work on the marks ASAP. Good luck!!! Kisses, truffles, M&Ms, dark chocolate bars, etc., they're all delicious!
