I recommend telling her NOT to stop in anymore. If that doesn't work, talk to your supervisor/HR - the message will be clearer coming from them.
Pack up ALL her stuff (drying rack, Halloween costume...etc.) and put it out on the porch or in the garage. Tell her she has one chance to get anything else. Don't let her continually come by to pick things up...better to rip the band-aid right off...the trickle of tag-ups isn't helpful for your emotions.
Does this sound counter-intuitive to you? If it does then do it.
Setting up healthy boundaries is part of the process. Those are two good boundaries.
One of my frustrations with most posters is they get great advise and then they ignore it and do what they feel like. Don't be like most posters.
