Tucked away

I have this habit of tucking things away.  As storage solutions go, it's not always great because I end up wondering for months at a time where something that I once designated "precious" is tucked away.
But every once in a while, I end up stumbling on something that has been tucked away for a long time that I have completely forgotten about, and it is so great to see it in plain sight and hold it in my hands again after its months or years of it being hidden. Sometimes those treasures get re-incorporated with all the untucked away stuff, but other times they get ushered back into a darkened handbag or in a drawer or box of other treasures once again.
What have you got tucked away?
