Medium — logic-grid deduction puzzle
At a paper stall during heritage week, two first-timers and two old hands made sheets, pressed something from a basket into them and turned them into keepsakes.
Heritage week in the port city ended with an open day of hand-made paper stalls on the harbour square. At one stall, an old craftswoman let visitors dip a bamboo screen into a vat of pulp and lift out wet sheets. Minji and Hayun had never tried it before, and they splashed water all over their shoes. Jiho and Seojun grew up helping in paper workshops, and their screens barely dripped. Two baskets stood by the vat. One held maple and ginkgo from the temple garden. The other held rose and daisy from the harbour market. Each of them took something different to press into the wet paper. When the sheets were dry, each one turned their stack into something to take home. No two of them made the same number of sheets.
