ditty bag (n.)

"水手用于存放针、线、剪刀、顶针等小物件的小袋子"，1828年，航海俚语，起源不明，可能来自所谓的英国海军短语 commodity bag。因此也有 ditty-box（1841）。

Every true man-of-war's man knows how to cut out clothing with as much ease, and producing as correct a fit, as the best tailor. This is a necessity on board ship, for the ready-made clothing procured of the purser is never known to fit, being generally manufactured several sizes larger than necessary, in order that it may be re-cut and made in good style. [Charles Nordhoff, "The Young Man-of-War's Man," 1866]

每个真正的军舰水手都知道如何轻松地裁剪衣服，并且能够做出与最好的裁缝一样合身的衣服。这是在船上的必要技能，因为从军需官那里购买的成衣通常不合身，通常比实际需要的尺寸大几个尺码，以便可以重新裁剪并制作成好的样式。[查尔斯·诺德霍夫，《年轻的军舰水手》，1866年]
