I hope you shortened your stitches and folded the paper before trying to remove it.
Also I hope you used a thin paper and not computer paper. I tend to use 25% rag vellum that I got on sale from Staples years ago. Still haven't used it all up yet. I have also used that thin drawing paper from pads meant for children. I haven't used it but know that exam table paper also works.
Have fun.
