Homemade lavender toilet water

I made this a few weeks ago, and it's ready to use now. I'm not certain where I read about it, possibly in one of the Reader's Digest home books. It's made with 7 fl oz of vodka, 2 fl oz of water and lavender essential oil - I can't remember how many drops, but I added a lot more than the book said. I also added a drop of blue and red food colouring, to give it a lavender tint. Mix in a jar and shake, then leave for at least two weeks.
It gives a very light perfume, but is lovely and refreshing, especially a dab or two on the temples; relieved a headache for me yesterday, so worth making for that use alone.
You could try any other favourite essential oils too, to ring the changes and for different moods.
Give it a go :)
