I hand quilt and generally use purchased stencils. I have made my own stencils as well. Both of these products come off very easily, particularly when washed and work well with both purchased or made stencils. Since they are chalk based, they do have a tendency to wear off fairly easily so I now mainly mark as I go. Easier to do with hand quilting than machine I would guess.
With any of the products I've mentioned I've not had issues with marks not washing out. You need to test, obviously, not only for ease of removal but also to see what colors work best for you.
