I tried using it for my long arm, but the speed of machine makes chalk bounce off. I end up pouncing chalk on stencil then tracing with washout blue marker. I ask their sales rep at a quilt show and he told me to swipe the pouncer twice over the stencil then use cheap hairspray over design! I think that would gum up my needles plus fix the chalk where it would not brush off. I feel it was waste of money!
