怎么叠床笠

A page from a wordless flat-pack style instruction manual, printed in black line art on white paper, portrait format, explaining how to fold a fitted bedsheet. Title at the top in bold sans-serif: "FOLDING A FITTED SHEET". Six numbered steps in a 2×3 grid of boxes, each drawn in clean, even-weight technical line illustration with a simple cartoon person whose head is a plain oval: 1, holding the sheet up by two corners; 2, tucking one elasticated corner into another; 3, doing the same on the other side, with a small curved arrow; 4, the sheet tangled around the person, a large question mark beside them; 5, the person sitting on the floor in a heap of fabric; 6, the sheet rolled into a ball and pushed onto a shelf, with a big tick mark. Step numbers in large bold circles. A small parts box in the top right lists "1× sheet" and "1× patience". Generous white space, flat black lines, no shading, one pale grey as the only extra tone.
