i've had the blue water erasing markers not come out-
i've had some chalks not come out
i've had washable quilters pencil---not come out
but then again-i've had all of them also work perfectly-
i've had good luck with things my famous quilting pal has had horrible luck with-i've had her favorite marker ruin a quilt of mine---

each project each tool- needs to be tested.
