Pincushion
(重定向自Pin cushion)
A pincushion (or pin cushion) is a small cushion, typically 3–5 cm (1.2–2.0 in) across, which is used in sewing to store pins or needles with their heads protruding so as to take hold of them easily, collect them, and keep them organized.
Pincushions are typically filled tightly with stuffing, so as to hold pins rigidly once placed. Magnetic pin cushions are also sometimes used; though technically they are not "cushions", they serve the same basic function of holding pins neatly.
