i absolutely love it!!
i use it whenever i'm working with quilting stencils.
i think the other poster might have had a problem since the product pad was still new.
i find it works best after the quilt pad is broken in a bit. i had the same problem when i first got the pad.
then i just took a hair brush and brush the pad to loosen the fibers and i haven't had a problem since.
when i use the white chalk i just remove it with a hot iron and when i use the blue chalk you have to rinse it away (the hot iron doesn't work on the blue chalk).
i give the product 5 stars and i wouldn't want to quilt without it.
