How do you make a homemade hamster carrier?

I want to know how to make a homemade hamster carrier cause I don't want to buy one.|||I think the supplies are going to cost you more than the already made carriers at the stores. Seriously, just buy one at the store. It's made better. You wont know how reliable your homemade carrier is and it could break apart.|||This website has a great way to make your homemade carrier you can size it down a bit to your needs because its cage sized|||you could use a tupperware container lined with cotton fluff and put a lid on top that has plenty of holes...or you could just buy one
