This is what happened, I was about to pin it to the small box with my hammer when I decided to change the positioning of the box, and in one second it was gone. I have searched everywhere. I do not know what to do. I have no other 3mm long nails - I really need the one that dissapeared. For my small box project seen above;)
The box previously used to store silverspoons (I think) and will now be used to store, hmmm, stuff. Not sure if the box thinks it's progress. Nobody asked the box. I covered the lid with nostalgia stamps from Finland. Part of my vast childhood collection.
