Now I've got a missing-item mystery. I've had a six-inch, good-quality steel rule for years. I used it last night at the workbench, and today it's not there. I figured it must have fallen into the trash can, so I transferred ever item from that can to another, which was particularly messy, because this morning I had discarded a paint can with about 2 TBS of paint, poured into the can so that it would dry. Not there.
I thoroughly cleaned the shelf under the workbench, and the area below it, so I know it didn't fall there.
I'm determined to find it.
