Handy Midget Darning Cotton

Listen, this hits all my buttons: you've got a mini kit, neat in a sweet box with excellent graphics. You've got a kitten on it. You've got charming evidence of (very) light use by its original 1940s owner, who stuck the needle through the thread when she was done. In the 3.2 by 2.5 inch box are one dozen black wooden spools of darning cotton by Belding Heminway Corticelli, 2 ends-2 ply, in "Assorted Best Hosiery Colors" which, admittedly, are hard to tell apart. Taupe all round pretty much. It's the cutest isn't it?
