You may have to repeat this step several times to make sure that the seal is good enough to not allow any leakage. Lastly decorate the bottle on the outside, by adding a decorative hand lettered label and a few more dried flowers. Tie all of this to the bottle with the raffia or ribbon. I highly suggest here also to add a list of ingredients to your label, that way if any of your gift recipients have any allergies, they can make sure there is nothing in your bath oil that will cause them an allergic reaction. If you have used wheat germ oil for one of your base oils, you will not need to add the vitamin E, since it will already be there.
Vitamin E is a component of wheat germ.
Next add your essential oils, again check on the scent to make sure you are happy with the smell. And follow the remaining instructions for pouring the bath oil into the bottle and sealing. While these are just two basic ideas for bath oils, you can most certainly experiment a bit with different essential oils to get a scent that you are happy with. Most places that you will be able to visit directly should have samples out of the different essential oils that you can smell. It will be much easier to make a scent decision if you are able to smell ahead of time, what you will be adding to your bath oils.
