vfrtwice, Welcome to CBid....
keep in mind what xrundog said above when you go to installing your ceder interior liner...
I would also like to add that when you prep the interior of your cabinet. before installing the ceder I would recommend using a water based poly to seal the entire interior woods here is what I use in my shop and it is waterbased biodegradable and leaves no odor or residue behind...

if you know anyone in the hardwood flooring business you could get a small amount, enough for your project from them.. or from a local flooring company for your project... may have to barter a few cigars ;0)
I would then prep the interior surface with steel wool to rough it abit.. and then apply the poly with a sponge brush... this will seal the interior and keep moisture from possibly building up into the original wood of your cabinet...then apply you SC...
just my .02 cents Good Luck on your project!!!
