Cindy,
If you left it in the frame there is no way to keep the varnish from reaching right up to the frame. It would end up gluing the frame to the canvas. If ever removed - the frame would take part of the varnish (and paint) with it I bet. See if you can get the framers to take it out for you and put it back in for you - along with that nifty brown paper. Heck - see if the framers want to varnish it also.
