Sorry if this is somewhere else too, I couldn't find it. When it comes to notebooks I really enjoy the removeable covers. and I'd like to put them onto a new notebook since I've used every page of the book I have. But I'm at a loss for how to replace the paper. I can seem to buy JUST covers, but not JUST the notebook. Am I just looking in the wrong place or do I have to buy a WHOLE new notebook with covers included just to get the paper? I'd hate to just buy a random notebook with removeable covers just to toss the covers so I can reuse the ones I like.
