I've used the Crayola markers, and not had a problem. Usually light or dark blue on white or unbleached muslin.
I've used the disappearing blue markers, they sometimes disappear without water, and they can be permanent if they're exposed to heat (even the sun, I'm told)
I've used chalk, and never had a problem with removal. A little kitty bum takes it off every time. Usually before I get to the quilting.

That one had a chalked stencil in the middle of it. Not after she was done with it.
Seriously though, the bohin chalk markers are my current favorite.
