How do you store your newfound bulk paint purchase? Well you're obviously not going to want to open a tin gallon bucket and break out the paint stirrers every time you want to use it- unless that's what floats your boat. It's cool if you do.
But if you don't, then you would need to pour it into something smaller for easier use. Make sure you stir the paint very well when you get it! I personally use the clear restaurant style condiment bottles that I store in a shoe storage hanger on the back of my door. They work well for mixing and they're easy to pour into and out of.
You can use anything you want- face cream jars, baby food jars, empty paint bottles, empty gelato jars... I've used all of them and they work great! I poured my white paint into a gelato jar and now I want ice cream every time I paint with it. So I wouldn't advise that. Ok, yes I would (:
