Essential oil

I like Lavender its not overpowering and doesn't smell to manufactured.

I have lavender growing in he garden but suspect if I put some in a pan of water over stove the smell would be ok until the lavender was 'cooked' then it would vanish. I would hope that maybe using lavender essential oil the smell would linger for longer.

The orange peel and cinnamon did nowt! 

Essential oils would work well I think. You only need a few drops to scent a room.
