    This Is Why You Always Find Sewing Kits In Your Mother's Danish Butter Cookie Tins

    A delicious worldwide mystery, now solved.

    Kids around the world grew up with one thing in common: opening a tin of Danish butter cookies only to find needles and thread.

    Universal feeling: When you open the butter cookies tin box expecting cookies but see a sewing kit.

    But WHY though? What is it about these particular cookies that make them so attractive for sewing kits? Turns out there is an answer for this - all based on the history of packaging.

    See, back in the day, biscuit tins weren't very common. They were usually either sold loose in paper bags (which often led to breakage) or - thanks largely to Nabisco - sold in paper boxes.

    National Biscuit Company (now Nabisco)'s Uneeda Biscuits, created in 1896, is often heralded as the "birth of consumer packaging" for its innovative and moisture-proof packages - waxed paper lining inside paper cartons.

    Cookie tins, however, were not as common - until 1966, when Royal Dansk created their distinctive blue tins to keep their cookies fresh.

    Besides being high-quality, the tins were also often very pretty, so people kept them as collectibles. (And they still do, to this day.)

    During times of war, people were encouraged to reuse as much as possible, and not throw too much away.

    Those blue cookie tins gained a second life as possible storage.

    Sewing supplies were universal, and they were often small, fiddly, and round - the perfect items to store in a large round tin.

    And a new tradition was born.

    This information comes to you from my mother, whose tins always have cookies in them.
