true enough, but if you are turning aggressively it's easy to shear the paper - much easier to use a thin waste block if your wood is really valuable - 3/16 to 1/4 of scrap is plenty, glue it on for real, turn the shape, then just reverse and turn it off - if you are using a wood worm or a faceplate you need a bit more thickness, but getting little scraps of 2X4s from a construction site is a cheap way to get wood - you don't need hard maple or such for a waste block.
Or, you can hit the waste block with a chisel/hammer a bit on the waste side of the glue line and split it off.
Paper works fine if you are gentle
