From what store did you get the giant ball from? I was thinking of working on a Katamari cosplay also, and that ball is like perfect.
Sorry if you already answered this in the comments, I didn't bother to read all the pages :V

Sorry for the SUPER SUPER old reply!! 
Unfortunately I can't remember where I bought it from
If you are still interested, I can try searching through my emails!
But if you're just looking for a giant ball to use for a Katamari, I'd say googling "giant beachball" or "giant inflatable ball" will get you some good results!
