A Corner Bookmark

I noticed an old paper receipt lying flat on the wooden table, just beside a stack of notebooks. The paper felt crisp and clean, so I took a moment to think about what to do with it. Folding it slowly along the diagonal edge, I pressed the crease firmly until it formed a tidy little pocket triangle. It slid smoothly right onto the corner of the top page. It feels very nice to turn something simple into a practical little helper for later reading.
