For protection you can simply place cones in the corners of the house, supplementing them with suitable oils and simple spells. Or hang a wreath with cones on the door, blocking negative energies from entering the house.
Or you can use them to decorate a festive tree, as a symbol of fertility or blessing.
For the Fulfillment of a Desire
In this case, the cone is a symbol of the universe and its creative, creative forces that will help your hopes come true.
Take a pine cone. It is best if you find it yourself. Then write your cherished desire on a small piece of paper.

Fold a piece of paper and insert between the scales (can be planted on wax).
For a while, just meditate with a bump in your hands, imagining the ultimate goal of the spell.
Light a fire (in the fireplace or outside the house) to welcome the fire spirits and the sunshine. If you like, you can feed them some bread or fire incense.
Throw the cone into the fire with a short slander.
Something like:
“Spirits of fire, help my wish to come true as soon as possible.”
Watch how the bump burns. You can also imagine how your intentions rise to the sky with smoke from the fire, reaching the Universe.
I have always been drawn to pine cones in fact I have one on the shelf next to me which I have had for at least 10 years! 🙂
