Done that so many times that I decided to make a plan for my garage, where I would write a little note on when I had 'safely' stored something in that part of the garage. The first time that I wanted something that I knew I had spare of (heatproof oven bulbs) I went to look on my plan to find where I had put them, but couldn't find the bloody plan!
It turned up the day after I had bought new bulbs! I had taped it to the inside of my toolbox lid! (Not much good when I had put the lid down!) The most annoying thing was I must have looked at the plan hundreds of times when the toolbox was open, but just not mentally stored it in my brain as being there.
