I have hessian wallpaper in my old house which I've started to strip. The hessian layer it's self comes off really easy leaving the backing paper. Trouble is, the backing paper seems to be stuck on with industrial strength glue which doesn't want to budge. I can't use a steamer as it blows the plaster! It's takes about an hour just to strip off with a scaper an area the about 600mm square.
