There is a lot to consider when choosing how you want to mark your fabric or whatever it is your marking. With fabric we have issues of light to dark. Most importantly how do you get rid of it when you are done!!
There is disappearing by air, rub, water, damp cloth or iron. I'm a big lover of Frixion though I know many say it comes back in the cold. I don't live in the Arctic & I'm not putting fabric in the freezer so I'm not worrying about it.
We have markers that are pencils, pens, powders & even a kind of wax. It's an amazing assortment!
