Once I eventually find what I was looking for here is what I do......When originally looking I take note of the first place I went and tried to locate it. This place at the time seemed the most logical place for me to have put it, once I find the item it is returned to this first place I looked . I also with my iPhone take a picture of it in the place I placed it. This may sound silly but for me it really has worked. Many times when I went to look for this item once again I actually looked in this first place that logically comes to mind and there it was. If the spot I was wanting to place it did not seem to be the right fit, for example a Weller soldering tip in a spot were it could easily fall and get lost I put a 3x5 card there with it's location. With ham radio (for me anyway) I have found myself turning the shack upside down for an item I know I have but can't locate and the above ideas help me out a great deal. Are there any ideas my fellow ham's that you can add?
