Love your choice!!!
I usually combine the first image I get in mind with what I get after actually concentrating on the object. Or use a pendulum (I don't know if I'm any good at finding other peoples' things, though
First picture that came in mind was the teddy under the bed, at a relatively dark place, near boxes or box-like objects and 1-2 pieces of cloth. I'm off to work now, so I'll work more on it later.
