As the title says, how do you make your house smell nice? I hate our house's smell, it has smelt the same since we moved in 7 1/2 years ago and it reminds me of old people LOL! I have used those plug in things before, but don't know if they're a good idea with kids? I have also used one of those infusion thingys in my kitchen that worked OK. I'd like something that smells soft and makes the whole house smell nice.

So, what do you use?
