This is the current collection of tiny hats. The hat seen in the previous picture on the Wii remote is the hat on the far right of the picture.
The yellow-orange yarn is something that I got for 50% off because the label had fallen off of it. It's very soft, but I don't know what's in it. The multi-colored yarn is sock yarn. I have a pair of socks I crocheted in that same yarn, which are awesome. I'll post about them later.
