Button, button, who's got the button?

Like my mother and both of my grandmothers, I have a button jar. Mine isn't like theirs. It isn't a pristine buttons-only jar. No, it contains all the small bits of things I think I'm going to—and often do—need: picture-hangers, screws, nails, thumbtacks, the little packets of thread given out at hotels, and, of course, buttons. I have the spare buttons which come with some clothes as well as the buttons that have fallen off clothes.
Today, I looked for one of the latter, a button missing from a blazer I think I might be wearing soon. And I found it. The button was there in the jar, waiting to be sewn on again.

Lindy, by Aleta

So, however, were the aforementioned picture-hangers, several different sizes of them, one size perfect for hanging Lindy's portrait. You may remember my post of the portrait I commissioned from Canadian artist Aleta Karstad as a gift for Dick when he had surgery recently.
After finding the button, I was feeling quite successful and pleased with myself, so I decided to frame the portrait, using the floater frame Aleta sent me. I think it looks good near Dick's recliner, where he can see his darlin' girl even when she's outside in the yard.
But what did I do with the button?
It's gone. I've looked everywhere I think might be an even remotely possible place for me to have put it. (There's a convoluted sentence for you. You can tell my brain isn't working properly.)
No, I didn't put the button into the blazer pocket. No, I didn't put it with the needles and thread. Those would have been good places, but I looked, to no avail. Nor was it in any of the less-good places, such as drawers near the counter where I emptied out the button jar. I didn't even put it back into the button jar. I took everything out again, just to make sure. I checked my desk, and the table beside my recliner (although I haven't sat in my recliner yet today) and all surfaces near the chair on which the blazer is hanging.
I've looked in my bathroom, and the laundry room, and the bedroom. I've looked on the floor in the kitchen and in the front hall.
Next, I guess I'll look in the kitchen garbage container (eeuuww, ick) before I arrange to have Lindy's innards X-rayed, but first I'm going to sit down in my recliner to watch some Home & Garden television. I'm always so impressed by people who do things, and do them well.
