I collect...

Shortly after I was married I discovered McCoy pottery, mainly due to the name sake. I have a small collection that is scattered around the house. I've received pieces as gifts, picked some up at estate sales and searched them out on e-bay.
Most are re purposed to hold thingies (like this pot)...
or display thingies (like this planter)... some are quite useful (like my smiley face mug)... some just sit pretty in the hutch (like the pink baby booties)...

I collect them because they make me happy. What do you collect?
