Yep, been there, done that. If I could put it my $ .02 (two cents), I use the local free papper. If I can put a visual picture together for you. I split in half a wooden closet pole
(2" dia.) and screwed it back together after inserting one end of the newsprint. I use about 15 sheets at one time, this prevents bleeding through. After I'm done I roll it up for next. After using it for awile a can eather tear off the top sheets or replace them. I hope this is helpful.
