This business of being a Witch is a funny thing. On one hand, you must have absolute confidence in the truth of your words; so much so that the deepest part of you, where you are connected to the fluid underpinnings of reality will respond and make things as you say they are. On the other, you must have an absolute and unflinching dedication to the truth and that means looking honestly at your failures, taking your lumps, and learning from them.
This spell was an utter failure. Harm, grief, and sorrow were regular visitors to Baile Ard. That's where I woke up on the day that I endured the most sorrowful experience of my life so-far: the death of my Mother.
So, I don't offer this as a good example of protective magic. I offer this rather as a quaint remembrance of a time when I thought a safe home and a well-protected life were much simpler things to achieve.
Take a handful of salt from the kitchen and proceed to sprinkle it on the front or back doorsill while repeating the following charm:
I cast this salt upon the ground and by this act my spell is bound.Keep out all harm, grief, and sorrow on each today and each tomorrow! I mean this for this sill and door and throughout this house forever more! Heed this charm! Cause no harm! So mote it be!
I have since devised a new domestic ward spell which is far, far more demanding to cast and so-far, more effective.
