I have problems finding things too but it's usually my perception. I call my DH into the room and tell him I'm looking for something and he can usually see it. My room is fairly organized but things can be right in front of me and I don't see it. Not sure why this is.
Example - I just finished a t-shirt quilt for my grandson's graduation (if I can figure out how to post a pic I will). I was ready to "de-fuzz" it and couldn't find my lint roller. I looked in both of my rooms - no luck. So I had to have DH look and he found it and it was basically within my sight....
