Where the Hell are all my Needles?

I've finished knitting Danbyholm but I can't find a sewing up needle. Is there one lurking in the bottom of my Knitpicks Options bag? - Nope. Looked through the bag containing all my dpns - Nope. Is there one in the bottom of the knitting bag containing an unblocked but finished Skin of The Sea? - Nope. What about underneath all the Aran Weight Silk that's waiting for a suitable pattern? - Nope. In the sewing box with all the reels of thread? - Nope. In the tin containing all my pins?
I am reduced to wandering aimlessly around the house looking for places I might have left a sewing up needle.......
Where do you keep yours?
