It sounds like you have many exciting things in store for the full moon, @Susurrus! I hope any ritual or spell you choose goes well, and that you have a wonderful time making Moon Water! 
May your Moon Oil bring you many blessings, @AliceInWonderdab! Enjoy 
Ohh noo @Kasandra! Perhaps your kitty thought the Moon Water was much more tasty than the water in her bowl 
A good idea to put it up high this month!
Awesome information on this and next month’s full moons, @Missa- thanks so much for sharing your wisdom! 
Ohhh @CelestiaMoon, that sounds exciting! 
I hadn’t considered combining Moon Water and Moon Oil- would you mind sharing the benefits/properties of that combo? I’m very curious to learn more!
I would say it depends on your purpose and your skill with mixing potions 
.
Knowing that each moon phase has different magickal properties, each Moon Water could be considered as a separate ingredient or element of the spell. I don’t see why you couldn’t mix and match to make a blend that suits the purpose of your spell.
For example, for someone hoping to Get rid of the negative energies of an ex, they could consider:
-1/2 bottle of Waning Gibbous Moon Water (banishing, cleansing)
-1/4 bottle of First Quarter Moon Water (healing, dealing with the emotion of love)
-1/4 bottle of Full Moon Water (power boost, spell enhancement)

I’d say the idea of mixing Moon Waters can help fine-tune your blend to exactly suit the needs of your spell! It opens the door to many new possibilities. Thanks for bringing this up, @CelestiaMoon!
