Start saving all of your used liquid laundry detergent jugs. Wash them out, and set them to dry. Make sure they are perfectly dry. Grab a funnel and pour in your paint. Be sure to mark the jug. No more rusty lids, paint splatters from tapping the lids closed, dried-out paint or runs down the side of the can when pouring. The spout works great for dispensing paint. Just fill the jugs using a funnel and you’re good to go.
Some people store paint in mason jars, which I think is a waste of a perfectly good glass jar. These should be used for canning, making lanterns or other things - not storing paint.
