For Inconspicuous Spells
Use tea bags to create incognito spells!
You could buy pre-made blends of herbal tea that suit your needs, then open up the tea bag and supplement it with small amounts of additional ingredients and close it back up with needle and thread or a staple. Write the spell/symbol/sigil/etc on the outside of the bag or on the little tag. Then steep and consume if you’ve used all non-toxic ingredients, or add to a bath, etc. You could even put in it a bowl and scry with the liquid and do some tasseomancy with the tea leaves later!
You could also make your own tea bags with coffee filters
or parchment paper for cooking, just fold the ingredients inside and like before, staple or sew it closed! Sewing it closed adds the extra benefit of letting you dangle your own little tag off the end of the knot you tie and using a corresponding color of thread.
Now that I think of it, if the elements are your thing, you’ve got all the elements covered in one item: the heat of the tea for fire, the steam and fragrance for air, the herbs for earth, and the water for well … water! Similarly, this could be used as an offering if you use ingredients that appeal to whoever you’re making an offering to.
This is a damn clever idea.
