Abstract: Flat, or folded, colored and colorless, erasable highlighting sheet film, with options for pre-scored, pre-cut, perforated strip-lined, flat, folded, pocketed, adhesive and no tack versions, the method and apparatus of which are used for short and/or long term affixation of the highlighting sheet film to a substrate, and removal thereof at any time. During use, the sheet film protects the associated substrate and after removal preserves the privacy of personal notes, while optionally saving them for sharing with others in association with the same or duplicate substrate. In addition, the sheet film may be saved, indefinitely stored, cleaned, and/or reapplied without visible damage to any substrate. Optional apparatus used to provide a second layer/level/echelon of highlighting to the sheet film, or otherwise prepare it for use or reuse, include colored or colorless marking tools, cloth, adhesive means, templates, and/or cutting tools in varying combinations, but not limited to these combinations.
