I am a long arm quilter and I use the pounce pad with miracle chaulk in it all the time. I pounce the pad in holder on the roller of the machine and then you swipe the pad accross the stencil don't pounce it. it works great for me on any color but white since it is white. It is removed with steam. I have marked the whole quilt and then loaded in the machine and have marked as I went either way works it stays on until you steam it off.
hope you try it again.
