With the Golden Threads paper, I think you can "sew" without thread thru 15 layers. I have used it a few times, but last time I gave up because the foot kept ripping the paper and it was taking forever. I marked it instead and it was much less frustrating. My favorite marking method is using the Blue Line Eraser set. It's water soluble also, but it says the solution will stay out after drying and even take out ironed on marks. So far, it has come out of any fabric I've tried it on. You can always test on the back in a seam allowance.

This gadget is the best to remove the lines without using too much of the fluid. You can always refill it with water too.
