Opposites Do Attract!

Found this little box of love at an estate sale recently.  The tin oblong navy blue box called to me.  No exterior label or any glimpse of what might be inside.

Surprise! The box was formerly a "gun cleaning kit" with tools of the trade and instructions for performing such tasks....yet, it now was the home of a lovely little stash of wood spooled multi-colored thread!  

My question lies in:  At what point did the previous owner discover that a gun cleaning kit box could be the home for thread?  Who knew? 

It is true, opposites do attract!
