St. Nicholas of Myra (aka Santa Claus) always comes to my rescue whenever I have misplaced things.
.
Several times I suspect that he has placed the lost item in a very conspicuous place. In fact, I heard a tiny voice encouraging me to look in a place where I had previously looked twice. When I looked that third time, there it was, no dust on it. How it got there I have no clue, but it was not there the last two times I had looked.
.
My husband was puzzled too as he had joined in the search and had looked twice in the same place as I had done. Whenever my husband loses items, we both pray to St. Nicholas, and St. Nicholas is always quick to respond.
.
St. Nicholas of Myra, intercede to Christ God for us that we may be saved.
.
(Pray this prayer at least three times, with faith and hope in God.)

Ask St. Anthony to help you find it, and do three hail Mary's (or just keep doing them during the day). I lost my wedding ring while working all day all over the place in a 5 acre forest & fields. My wife reminded me to do the prayers and within 5 minutes I found the ring in the fields. An internal voice (a though)  will tell you where it is. 

I can tell you 100 more such stories of finding things this way. I use it all the time to find, my glasses, keys, tools, papers......
