Apply Initial Masking Paper

Today I got a handy tip for you and it's how to keep your overspray from running down your walls when you're spraying your trim if you've already painted your walls. What we would be doing is we'd be masking around this entire window and I'd be masking with just 9 in paper in my production tape. So I have this paper here. Now in order to keep the overspray from running down the wall, I'm just going to take pre fold my paper over and crease it.
