I got some really nice one's at b&m bargains they do seem a bit pricey at first but the ones that cost more are bigger! And they are really pretty! B&M Stores: when you go instore they have more fleece!
I have nothing helpful to add, but "Cookies Detecting" made me think of a guinea pig, named Cookie, who is being a detective, Sherlock Holmes style. The image in my head is pretty darn cute and funny, so I thought I'd share.
