Yes - I'm using the heat erasable Frixion Ball pen - you can just iron off your marking lines. But - the marks will reappear if the quilt gets cold unless the mark is completely removed with an ink remover - so I'm careful when using the pen to mark my quilting lines! 😀
I tried to send you a reply with a picture on the email I received but it didn't work. Midnight might not be the best time when I should be sleeping. Creativity doesn't watch the click!😊
