Was it Golden thread tracing paper? You could try their site to see what they recommend. If it was a kind of paper that was thicker, it will be harder to remove if you did close quilting. In that case I would say to use something like the pointed end of your stitch ripper to run along the lines of stitches to help loosen the paper. For super difficult paper to remove, I like my haemostats to grasp and pull. Good Luck
