How do I keep a used paint roller from drying out between uses: several days?

Take a few old grocery bags the plastic ones and wrap them in it, also foil is good as well. I like to use saran wrap or the plastic from dry cleaners. I find it works better. Make sure they stay as cool as possible.

This is correct for laytex paints, not oil,

Glavine I was speaking of latex, guess I should have noted. But, I've done this for oil if I am going to use it the next day. I dip the brush and wrap it while it is quite wet. I am not doing this for jobs that I am getting paid for this is in my own home with my own projects. I change colors quite often on things/walls and do most of the painting myself. However I am not a professional painter and I needed to mention that in my post.

My Names Not Galvine Lol. Its Glavine Lol. Yea I Figured It Was Laytex, Ive Tried It With Oil But It Did Work With Me, But I Didn't Dip It And Then Wrap It, I Can't Stand Oil, I Usually Just Through Every Thing Away After Im Done,
A New Brush A Day Will Keep Cleaning The Oily Brush Away

Wrap it in a plastic bag and put it in the freezer, thaw out when ready to use again. Works every time, fool proof

Take you a gallon size zip lock bag, place over the roller head, push out all the excess air you can and then put a rubber band around the open end.
