Maybe because I'm an office worker and I have to do lots of creative
tinkering with my supplies, I don't see why one can't use a piece of
thin-ish paper, cut a couple of inches wide and as long as necessary
for the circumference plus overlap, wrap it up tight and just use
a glue stick to tack it in place.  Won't touch the roll in any way,
can't bleed through.  I would put the glue on first to keep from
having to press on the roll.

Any problems?
