Offerings for the mermaids, the Merfolk .and sea spirits.
Here's an extensive list for you to choose from:
Roses and flowers
Scented natural soaps
Perfumes of essential oils
Silver gifts of beauty
Mermaids love anything that holds a lot of feminine energy
This is because they are the ultimate energy.
And this is a reflection of them .
Any of the gifts above are great
When performing great power rituals, you should with the number 7
As in give 7 peices of silver
Or 7 crystals
REMEMBER number 7 is the number of the Merfolk and Fae
Try to work with the number 7 whenever you can
Of course ,you don't always have to
As this can start to be very expensive.
But in my workings of the Merfolk
They will bless you always with Abundance for your love and work with them.
So therfore you should always bless them back in return .
