Sizing vs. matching paint for wallpaper
I'm having some wallpaper put up in my bedroom (one of the only jobs I will NOT undertake myself). In the past I haved always sized the wall, but one of the guys who came in to do an estimate said I should paint the wall (that the paper is covering) the same color as the wallpaper (in this case a deep red) ... because he says inevitably the paper might shrink and seeing white will be more obvious than a similiar color red.
Now this is the first time I've heard this - I've always heard of sizing, never the other. This guy came with good recommendations other wise I'd assuming he's asking me to help mask his mistakes. Anybody have any input to add to this?
