Hi there Mrs. Blue... glad you like the hidden mickey idea..take it away..
What I did was use black construction paper and cut out one circle (for the head) and two smaller ones (for the ears) I decorated them w/ my glitter pens (yes, I have way to much time on my hands) each one with a descending number.(or you could use the home depot paint chips I guess..) Then everyday I would hide one around the house for my dh (yes, 41yrs old and still enjoys this game) He would usually find it in the Am, if by the pm he hadnt found it he would start walking around saying "wheres my mickey"... (wonder what the neighbors thought about that?)

just kidding..
Everyday I would hide one... some places I used were taped to the inside of the shower, in the microwave, taped to his rearview mirror, inbetween his folded napkin, in his reading book..
but my all time favorite was when I taped it to the inside lid of the toilet....he almost pee'd on mickey!!!
This year I am going w/ my mom so I gave them to my dad to hide for her.
