Eggshells are a really great and inexpensive thing to use in your craft. Just save the shells, wash them out, and grind them into a fine powder. They can be used to make a circle outside, in protection spells, and to help your plants grow!

I've got a ton of eggshells sitting on my desk xD but I haven't been able to find the mortar and pestle I know we have in our kitchen... somewhere.
I'm guessing because they're good for plants it's better to use eggshell powder instead of salt as an offering to spirits/nature etc (I read a lot of people suggest salt as an offering)
A bit of A level science: Salt decreases water potential in the soil. Basically pure water has a water potential of zero and any solutes in water causes water potential to decrease/become more negative. Water always moves towards areas of more negative water potential (this is partly how plants take up water, the water potential inside their root cells is more negative). This is why it's bad to use too much fertiliser because water from inside the plant will then move out of the plant, same principle with salt.
