I designed a logo for a friend last year and got a sweet thank you in the form of a gift certificate for a local spa.  After treating myself and my sister to pedis, I spent the rest of the gift certificate on essential oils.  I think I purchased about 12 or 15 different oils.  I just love essential oils and mixing up little lovelies with them.  Last night I made a calming oil blend that I applied all over, and it helped me drift right off to sleep. :)  Always make sure you avoid your eyes when applying.  Don't ingest this oil blend - for external use only!!
Ingredients
1/3 cup oil* (I used grapeseed)
5 drops vanilla essential oil
5-7 drops lavender essential oil
Directions
Pour oil into a clean plastic or glass container.  Make sure your container has a lid!  Add essential oil 1 drop at a time, vanilla first and then 5 drops of lavender.  Shake well (put the lid on first!!) and sniff.  Add more lavender, 1 drop at a time, shaking and smelling as you go.  Apply!
This would make a great gift!  To make a coordinating body scrub, simply add 3-4 TBSP of brown sugar to the recipe above and store in a wide-mouthed plastic container with lid.
*I use whatever oil I have on hand.  I always have olive oil and almost always have grapeseed oil.  I would not recommend using canola oil or similar oils.  I have also used sweet almond oil, which is lovely.  My favourite right now is grapeseed for a couple of reasons: (1) my skin likes it, (2) doesn't smell too oily, (3) absorbs quickly, and (4) it's not too greasy.
