Hiya Kit.
I have no experience with oil but thought that I would let you know what I have been using over the last 5 years so as you might want to try and experiement with whats available to find something that suits you.
I use Biotone massage lotion and creams. There are many types available from different companies and all can be mixed with essential oils too.
Biotone is provided by the Massage Table store and also Russell Medical, both found on the net.
Oils, dependant on what types, sometimes stain the drapes you use unless you buy products to eliminate that in the wash... or of course use diposable paper roll..
I worked at a clinic once where all the therapists used oils and no one seemed to clean up properly and even the door handles were covered in oil... as for the sheets and pillows!!!!!
Biotone is water based and washes out very easily lewaving no stains
Just thought I would throw that in to the conversatiopn so as you know of other stuff that is available, however if the course work is taught using oil then you would probably need to go with what they are working with.
